Lonami Exo f8264abb5a Clean-up client's __init__ and remove entity cache 
Entity cache uses are removed. It was a source of ever-growing memory
usage that has to be reworked. This affects everything that tried to
obtain an input entity, input sender or input chat (such as the
SenderGetter or calls to _get_entity_pair). Input entities need to be
reworked in any case.

Its removal also affects the automatic cache of any raw API request.

Raise last error parameter is removed, and its behaviour made default.

The connection type parameter has been removed, since users really have
no need to change it.

A few more attributes have been made private, since users should not
mess with those.

"""
Arguments
session (`str` | `telethon.sessions.abstract.Session`, `None`):
The file name of the session file to be used if a string is
given (it may be a full path), or the Session instance to be
used otherwise. If it's `None`, the session will not be saved,
and you should call :meth:`.log_out()` when you're done.
Note that if you pass a string it will be a file in the current
working directory, although you can also pass absolute paths.
The session file contains enough information for you to login
without re-sending the code, so if you have to enter the code
more than once, maybe you're changing the working directory,
renaming or removing the file, or using random names.
api_id (`int` | `str`):
The API ID you obtained from https://my.telegram.org.
api_hash (`str`):
The API hash you obtained from https://my.telegram.org.
connection (`str`, optional):
The connection mode to be used when creating a new connection
to the servers. The available modes are:
* ``'full'``
* ``'intermediate'``
* ``'abridged'``
* ``'obfuscated'``
* ``'http'``
Defaults to `telethon.network.connection.tcpfull.ConnectionTcpFull`.
use_ipv6 (`bool`, optional):
Whether to connect to the servers through IPv6 or not.
By default this is `False` as IPv6 support is not
too widespread yet.
proxy (`tuple` | `list` | `dict`, optional):
An iterable consisting of the proxy info. If `connection` is
one of `MTProxy`, then it should contain MTProxy credentials:
``('hostname', port, 'secret')``. Otherwise, it's meant to store
function parameters for PySocks, like ``(type, 'hostname', port)``.
See https://github.com/Anorov/PySocks#usage-1 for more.
local_addr (`str` | `tuple`, optional):
Local host address (and port, optionally) used to bind the socket to locally.
You only need to use this if you have multiple network cards and
want to use a specific one.
timeout (`int` | `float`, optional):
The timeout in seconds to be used when connecting.
This is **not** the timeout to be used when ``await``'ing for
invoked requests, and you should use ``asyncio.wait`` or
``asyncio.wait_for`` for that.
request_retries (`int` | `None`, optional):
How many times a request should be retried. Request are retried
when Telegram is having internal issues (due to either
``errors.ServerError`` or ``errors.RpcCallFailError``),
when there is a ``errors.FloodWaitError`` less than
`flood_sleep_threshold`, or when there's a migrate error.
May take a negative or `None` value for infinite retries, but
this is not recommended, since some requests can always trigger
a call fail (such as searching for messages).
connection_retries (`int` | `None`, optional):
How many times the reconnection should retry, either on the
initial connection or when Telegram disconnects us. May be
set to a negative or `None` value for infinite retries, but
this is not recommended, since the program can get stuck in an
infinite loop.
retry_delay (`int` | `float`, optional):
The delay in seconds to sleep between automatic reconnections.
auto_reconnect (`bool`, optional):
Whether reconnection should be retried `connection_retries`
times automatically if Telegram disconnects us or not.
sequential_updates (`bool`, optional):
By default every incoming update will create a new task, so
you can handle several updates in parallel. Some scripts need
the order in which updates are processed to be sequential, and
this setting allows them to do so.
If set to `True`, incoming updates will be put in a queue
and processed sequentially. This means your event handlers
should *not* perform long-running operations since new
updates are put inside of an unbounded queue.
flood_sleep_threshold (`int` | `float`, optional):
The threshold below which the library should automatically
sleep on flood wait and slow mode wait errors (inclusive). For instance, if a
``FloodWaitError`` for 17s occurs and `flood_sleep_threshold`
is 20s, the library will ``sleep`` automatically. If the error
was for 21s, it would ``raise FloodWaitError`` instead. Values
larger than a day (like ``float('inf')``) will be changed to a day.
raise_last_call_error (`bool`, optional):
When API calls fail in a way that causes Telethon to retry
automatically, should the RPC error of the last attempt be raised
instead of a generic ValueError. This is mostly useful for
detecting when Telegram has internal issues.
device_model (`str`, optional):
"Device model" to be sent when creating the initial connection.
Defaults to 'PC (n)bit' derived from ``platform.uname().machine``, or its direct value if unknown.
system_version (`str`, optional):
"System version" to be sent when creating the initial connection.
Defaults to ``platform.uname().release`` stripped of everything ahead of -.
app_version (`str`, optional):
"App version" to be sent when creating the initial connection.
Defaults to `telethon.version.__version__`.
lang_code (`str`, optional):
"Language code" to be sent when creating the initial connection.
Defaults to ``'en'``.
system_lang_code (`str`, optional):
"System lang code" to be sent when creating the initial connection.
Defaults to `lang_code`.
base_logger (`str` | `logging.Logger`, optional):
Base logger name or instance to use.
If a `str` is given, it'll be passed to `logging.getLogger()`. If a
`logging.Logger` is given, it'll be used directly. If something
else or nothing is given, the default logger will be used.
receive_updates (`bool`, optional):
Whether the client will receive updates or not. By default, updates
will be received from Telegram as they occur.
Turning this off means that Telegram will not send updates at all
so event handlers and QR login will not work. However, certain
scripts don't need updates, so this will reduce the amount of
bandwidth used.

Begin a takeout session. All subsequent requests made by the client
will be behind a takeout session. The takeout session will persist
in the session file, until `TelegramClient.end_takeout` is used.
When the takeout session is enabled, some requests will have lower
flood limits. This is useful if you want to export the data from
conversations or mass-download media, since the rate limits will
be lower. Only some requests will be affected, and you will need
to adjust the `wait_time` of methods like `client.iter_messages
<telethon.client.messages.MessageMethods.iter_messages>`.
By default, all parameters are `None`, and you need to enable those
you plan to use by setting them to either `True` or `False`.
You should ``except errors.TakeoutInitDelayError as e``, since this
exception will raise depending on the condition of the session. You
can then access ``e.seconds`` to know how long you should wait for
before calling the method again.
If you want to ignore the currently-active takeout session in a task,
toggle the following context variable:
.. code-block:: python
telethon.ignore_takeout.set(True)
An error occurs if ``TelegramClient.takeout_active`` was already ``True``.
Arguments
contacts (`bool`):
Set to `True` if you plan on downloading contacts.
users (`bool`):
Set to `True` if you plan on downloading information
from users and their private conversations with you.
chats (`bool`):
Set to `True` if you plan on downloading information
from small group chats, such as messages and media.
megagroups (`bool`):
Set to `True` if you plan on downloading information
from megagroups (channels), such as messages and media.
channels (`bool`):
Set to `True` if you plan on downloading information
from broadcast channels, such as messages and media.
files (`bool`):
Set to `True` if you plan on downloading media and
you don't only wish to export messages.
max_file_size (`int`):

Iterator over a user's profile photos or a chat's photos.
The order is from the most recent photo to the oldest.
Arguments
entity (`entity`):
The entity from which to get the profile or chat photos.
limit (`int` | `None`, optional):
Number of photos to be retrieved.
The limit may also be `None`, which would eventually all
the photos that are still available.
By default, there is no limit set when using the result as
an iterator. When using ``await``, the default limit is 1,

offset (`int`):
How many photos should be skipped before returning the first one.
max_id (`int`):
The maximum ID allowed when fetching photos.
Yields
Instances of :tl:`Photo`.

Returns a context-manager object to represent a "chat action".
Chat actions indicate things like "user is typing", "user is
uploading a photo", etc.
If the action is ``'cancel'``, you should just ``await`` the result,
since it makes no sense to use a context-manager for it.
See the example below for intended usage.
Arguments
entity (`entity`):
The entity where the action should be showed in.
action (`str` | :tl:`SendMessageAction`):
The action to show. You can either pass a instance of
:tl:`SendMessageAction` or better, a string used while:
* ``'typing'``: typing a text message.
* ``'contact'``: choosing a contact.
* ``'game'``: playing a game.
* ``'location'``: choosing a geo location.
* ``'sticker'``: choosing a sticker.
* ``'record-audio'``: recording a voice note.
You may use ``'record-voice'`` as alias.
* ``'record-round'``: recording a round video.
* ``'record-video'``: recording a normal video.
* ``'audio'``: sending an audio file (voice note or song).
You may use ``'voice'`` and ``'song'`` as aliases.
* ``'round'``: uploading a round video.
* ``'video'``: uploading a video file.
* ``'photo'``: uploading a photo.
* ``'document'``: uploading a document file.
You may use ``'file'`` as alias.
* ``'cancel'``: cancel any pending action in this chat.
Invalid strings will raise a ``ValueError``.
delay (`int` | `float`):
The delay, in seconds, to wait between sending actions.
For example, if the delay is 5 and it takes 7 seconds to
do something, three requests will be made at 0s, 5s, and
7s to cancel the action.
auto_cancel (`bool`):
Whether the action should be cancelled once the context
manager exists or not. The default is `True`, since
you don't want progress to be shown when it has already

Raises an error if a wrong combination of rights are given
(e.g. you don't have enough permissions to revoke one).
By default, each boolean argument is `True`, meaning that it
is true that the user has access to the default permission

If you set an argument to `False`, then a restriction is applied
regardless of the default permissions.
It is important to note that `True` does *not* mean grant, only
"don't restrict", and this is where the default permissions come
in. A user may have not been revoked the ``pin_messages`` permission

user (`entity`, optional):
If specified, the permission will be changed for the specific user.
If left as `None`, the default chat permissions will be updated.
until_date (`DateLike`, optional):

If the due date or duration is longer than 366 days or shorter than
30 seconds, the ban will be forever. Defaults to ``0`` (ban forever).
view_messages (`bool`, optional):

Note that values outside the valid range will be clamped,

"""
Iterator over the messages for the given chat.
The default order is from newest to oldest, but this
behaviour can be changed with the `reverse` parameter.
If either `search`, `filter` or `from_user` are provided,
:tl:`messages.Search` will be used instead of :tl:`messages.getHistory`.
.. note::
Telegram's flood wait limit for :tl:`GetHistory` seems to
be around 30 seconds per 10 requests, therefore a sleep of 1
second is the default for this limit (or above).
Arguments
entity (`entity`):
The entity from whom to retrieve the message history.
It may be `None` to perform a global search, or
to get messages by their ID from no particular chat.
Note that some of the offsets will not work if this
is the case.
Note that if you want to perform a global search,
you **must** set a non-empty `search` string, a `filter`.
or `from_user`.
limit (`int` | `None`, optional):
Number of messages to be retrieved. Due to limitations with
the API retrieving more than 3000 messages will take longer
than half a minute (or even more based on previous calls).
The limit may also be `None`, which would eventually return
the whole history.
By default, there is no limit set when using the result as
an iterator. When using ``await``, the default limit is 1,
so the method returns the last message.
offset_date (`datetime`):
Offset date (messages *previous* to this date will be
retrieved). Exclusive.
offset_id (`int`):
Offset message ID (only messages *previous* to the given
ID will be retrieved). Exclusive.
max_id (`int`):
All the messages with a higher (newer) ID or equal to this will
be excluded.
min_id (`int`):
All the messages with a lower (older) ID or equal to this will
be excluded.
add_offset (`int`):
Additional message offset (all of the specified offsets +
this offset = older messages).
search (`str`):
The string to be used as a search query.
filter (:tl:`MessagesFilter` | `type`):
The filter to use when returning messages. For instance,
:tl:`InputMessagesFilterPhotos` would yield only messages
containing photos.
from_user (`entity`):
Only messages from this entity will be returned.
wait_time (`int`):
Wait time (in seconds) between different
:tl:`GetHistory`. Use this parameter to avoid hitting
the ``FloodWaitError`` as needed. If left to `None`, it will
default to 1 second only if the limit is higher than 3000.
If the ``ids`` parameter is used, this time will default
to 10 seconds only if the amount of IDs is higher than 300.
ids (`int`, `list`):
A single integer ID (or several IDs) for the message that
should be returned. This parameter takes precedence over
the rest (which will be ignored if this is set). This can
for instance be used to get the message with ID 123 from
a channel. Note that if the message doesn't exist, `None`
will appear in its place, so that zipping the list of IDs
with the messages can match one-to-one.
.. note::
At the time of writing, Telegram will **not** return
:tl:`MessageEmpty` for :tl:`InputMessageReplyTo` IDs that
failed (i.e. the message is not replying to any, or is
replying to a deleted message). This means that it is
**not** possible to match messages one-by-one, so be
careful if you use non-integers in this parameter.
reverse (`bool`, optional):
If set to `True`, the messages will be returned in reverse
order (from oldest to newest, instead of the default newest
to oldest). This also means that the meaning of `offset_id`
and `offset_date` parameters is reversed, although they will
still be exclusive. `min_id` becomes equivalent to `offset_id`
instead of being `max_id` as well since messages are returned
in ascending order.
You cannot use this if both `entity` and `ids` are `None`.
reply_to (`int`, optional):
If set to a message ID, the messages that reply to this ID
will be returned. This feature is also known as comments in
posts of broadcast channels, or viewing threads in groups.
This feature can only be used in broadcast channels and their
linked megagroups. Using it in a chat or private conversation
will result in ``telethon.errors.PeerIdInvalidError`` to occur.
When using this parameter, the ``filter`` and ``search``
parameters have no effect, since Telegram's API doesn't
support searching messages in replies.
.. note::
This feature is used to get replies to a message in the
*discussion* group. If the same broadcast channel sends
a message and replies to it itself, that reply will not
be included in the results.
scheduled (`bool`, optional):
If set to `True`, messages which are scheduled will be returned.
All other parameter will be ignored for this, except `entity`.
Yields
Instances of `Message <telethon.tl._custom.message.Message>`.

"""
Sends a Message to the specified user, chat or channel.
The message can be either a string or a previous Message instance.
If it's a previous Message instance, the rest of parameters will be ignored.
If it's not, a Message instance will be constructed, and send_to used.
Sending a ``/start`` command with a parameter (like ``?start=data``)
is also done through this method. Simply send ``'/start data'`` to
the bot.
See also `Message.respond() <telethon.tl._custom.message.Message.respond>`
and `Message.reply() <telethon.tl._custom.message.Message.reply>`.
Arguments
entity (`entity`):
To who will it be sent.
message (`str` | `Message <telethon.tl._custom.message.Message>`):
The message to be sent, or another message object to resend.
The maximum length for a message is 35,000 bytes or 4,096
characters. Longer messages will not be sliced automatically,
and you should slice them manually if the text to send is
longer than said length.
reply_to (`int` | `Message <telethon.tl._custom.message.Message>`, optional):
Whether to reply to a message or not. If an integer is provided,
it should be the ID of the message that it should reply to.
attributes (`list`, optional):
Optional attributes that override the inferred ones, like
:tl:`DocumentAttributeFilename` and so on.
parse_mode (`object`, optional):
See the `TelegramClient.parse_mode
<telethon.client.messageparse.MessageParseMethods.parse_mode>`
property for allowed values. Markdown parsing will be used by
default.
formatting_entities (`list`, optional):
A list of message formatting entities. When provided, the ``parse_mode`` is ignored.
link_preview (`bool`, optional):
Should the link preview be shown?
file (`file`, optional):
Sends a message with a file attached (e.g. a photo,
video, audio or document). The ``message`` may be empty.
thumb (`str` | `bytes` | `file`, optional):
Optional JPEG thumbnail (for documents). **Telegram will
ignore this parameter** unless you pass a ``.jpg`` file!
The file must also be small in dimensions and in disk size.
Successful thumbnails were files below 20kB and 320x320px.
Width/height and dimensions/size ratios may be important.
For Telegram to accept a thumbnail, you must provide the
dimensions of the underlying media through ``attributes=``
with :tl:`DocumentAttributesVideo` or by installing the
optional ``hachoir`` dependency.
force_document (`bool`, optional):
Whether to send the given file as a document or not.
clear_draft (`bool`, optional):
Whether the existing draft should be cleared or not.
buttons (`list`, `_custom.Button <telethon.tl._custom.button.Button>`, :tl:`KeyboardButton`):
The matrix (list of lists), row list or button to be shown
after sending the message. This parameter will only work if
you have signed in as a bot. You can also pass your own
:tl:`ReplyMarkup` here.
All the following limits apply together:
* There can be 100 buttons at most (any more are ignored).
* There can be 8 buttons per row at most (more are ignored).
* The maximum callback data per button is 64 bytes.
* The maximum data that can be embedded in total is just
over 4KB, shared between inline callback data and text.
silent (`bool`, optional):
Whether the message should notify people in a broadcast
channel or not. Defaults to `False`, which means it will
notify them. Set it to `True` to alter this behaviour.
background (`bool`, optional):
Whether the message should be send in background.
supports_streaming (`bool`, optional):
Whether the sent video supports streaming or not. Note that
Telegram only recognizes as streamable some formats like MP4,
and others like AVI or MKV will not work. You should convert
these to MP4 before sending if you want them to be streamable.
Unsupported formats will result in ``VideoContentTypeError``.
schedule (`hints.DateLike`, optional):
If set, the message won't send immediately, and instead
it will be scheduled to be automatically sent at a later
time.
comment_to (`int` | `Message <telethon.tl._custom.message.Message>`, optional):
Similar to ``reply_to``, but replies in the linked group of a
broadcast channel instead (effectively leaving a "comment to"
the specified message).
This parameter takes precedence over ``reply_to``. If there is
no linked chat, `telethon.errors.sgIdInvalidError` is raised.
Returns
The sent `_custom.Message <telethon.tl._custom.message.Message>`.
Example
.. code-block:: python
# Markdown is the default
await client.send_message('me', 'Hello **world**!')
# Default to another parse mode

See also `Message.forward_to() <telethon.tl._custom.message.Message.forward_to>`.
Arguments
entity (`entity`):

from_peer (`entity`):
If the given messages are integer IDs and not instances
of the ``Message`` class, this *must* be specified in

disconnection occurs, and keeps your code running if you have nothing

Manual disconnections can be made by calling `disconnect()

``KeyboardInterrupt`` by pressing ``Ctrl+C`` on the console window

Sends message with the given file to the specified entity.
.. note::
If the ``hachoir3`` package (``hachoir`` module) is installed,
it will be used to determine metadata from audio and video files.
If the ``pillow`` package is installed and you are sending a photo,
it will be resized to fit within the maximum dimensions allowed
by Telegram to avoid ``errors.PhotoInvalidDimensionsError``. This
cannot be done if you are sending :tl:`InputFile`, however.
Arguments
entity (`entity`):
Who will receive the file.
file (`str` | `bytes` | `file` | `media`):
The file to send, which can be one of:
* A local file path to an in-disk file. The file name
will be the path's base name.
* A `bytes` byte array with the file's data to send
(for example, by using ``text.encode('utf-8')``).
A default file name will be used.
* A bytes `io.IOBase` stream over the file to send
(for example, by using ``open(file, 'rb')``).
Its ``.name`` property will be used for the file name,
or a default if it doesn't have one.
* An external URL to a file over the internet. This will
send the file as "external" media, and Telegram is the
one that will fetch the media and send it.
* A handle to an existing file (for example, if you sent a
message with media before, you can use its ``message.media``
as a file here).
* A handle to an uploaded file (from `upload_file`).
* A :tl:`InputMedia` instance. For example, if you want to
send a dice use :tl:`InputMediaDice`, or if you want to
send a contact use :tl:`InputMediaContact`.
To send an album, you should provide a list in this parameter.
If a list or similar is provided, the files in it will be
sent as an album in the order in which they appear, sliced
in chunks of 10 if more than 10 are given.
caption (`str`, optional):
Optional caption for the sent media message. When sending an
album, the caption may be a list of strings, which will be
assigned to the files pairwise.
force_document (`bool`, optional):
If left to `False` and the file is a path that ends with
the extension of an image file or a video file, it will be
sent as such. Otherwise always as a document.
file_size (`int`, optional):
The size of the file to be uploaded if it needs to be uploaded,
which will be determined automatically if not specified.
If the file size can't be determined beforehand, the entire
file will be read in-memory to find out how large it is.
clear_draft (`bool`, optional):
Whether the existing draft should be cleared or not.
progress_callback (`callable`, optional):
A callback function accepting two parameters:
``(sent bytes, total)``.
reply_to (`int` | `Message <telethon.tl._custom.message.Message>`):
Same as `reply_to` from `send_message`.
attributes (`list`, optional):
Optional attributes that override the inferred ones, like
:tl:`DocumentAttributeFilename` and so on.
thumb (`str` | `bytes` | `file`, optional):
Optional JPEG thumbnail (for documents). **Telegram will
ignore this parameter** unless you pass a ``.jpg`` file!
The file must also be small in dimensions and in disk size.
Successful thumbnails were files below 20kB and 320x320px.
Width/height and dimensions/size ratios may be important.
For Telegram to accept a thumbnail, you must provide the
dimensions of the underlying media through ``attributes=``
with :tl:`DocumentAttributesVideo` or by installing the
optional ``hachoir`` dependency.
allow_cache (`bool`, optional):
This parameter currently does nothing, but is kept for
backward-compatibility (and it may get its use back in
the future).
parse_mode (`object`, optional):
See the `TelegramClient.parse_mode
<telethon.client.messageparse.MessageParseMethods.parse_mode>`
property for allowed values. Markdown parsing will be used by
default.
formatting_entities (`list`, optional):
A list of message formatting entities. When provided, the ``parse_mode`` is ignored.
voice_note (`bool`, optional):
If `True` the audio will be sent as a voice note.
video_note (`bool`, optional):
If `True` the video will be sent as a video note,
also known as a round video message.
buttons (`list`, `_custom.Button <telethon.tl._custom.button.Button>`, :tl:`KeyboardButton`):
The matrix (list of lists), row list or button to be shown
after sending the message. This parameter will only work if
you have signed in as a bot. You can also pass your own
:tl:`ReplyMarkup` here.
silent (`bool`, optional):
Whether the message should notify people with sound or not.
Defaults to `False` (send with a notification sound unless
the person has the chat muted). Set it to `True` to alter
this behaviour.
background (`bool`, optional):
Whether the message should be send in background.
supports_streaming (`bool`, optional):
Whether the sent video supports streaming or not. Note that
Telegram only recognizes as streamable some formats like MP4,
and others like AVI or MKV will not work. You should convert
these to MP4 before sending if you want them to be streamable.
Unsupported formats will result in ``VideoContentTypeError``.
schedule (`hints.DateLike`, optional):
If set, the file won't send immediately, and instead
it will be scheduled to be automatically sent at a later
time.
comment_to (`int` | `Message <telethon.tl._custom.message.Message>`, optional):
Similar to ``reply_to``, but replies in the linked group of a
broadcast channel instead (effectively leaving a "comment to"
the specified message).
This parameter takes precedence over ``reply_to``. If there is
no linked chat, `telethon.errors.sgIdInvalidError` is raised.
ttl (`int`. optional):
The Time-To-Live of the file (also known as "self-destruct timer"
or "self-destructing media"). If set, files can only be viewed for
a short period of time before they disappear from the message
history automatically.
The value must be at least 1 second, and at most 60 seconds,
otherwise Telegram will ignore this parameter.
Not all types of media can be used with this parameter, such
as text documents, which will fail with ``TtlMediaInvalidError``.
Returns
The `Message <telethon.tl._custom.message.Message>` (or messages)
containing the sent file, or messages if a list of them was passed.
Example
.. code-block:: python
# Normal files like photos
await client.send_file(chat, '/my/photos/me.jpg', caption="It's me!")

If not specified, the name will be taken from the ``file``

use_cache (`type`, optional):
This parameter currently does nothing, but is kept for
backward-compatibility (and it may get its use back in

Arguments
entity (`str` | `int` | :tl:`Peer` | :tl:`InputPeer`):
If a username is given, **the username will be resolved** making
an API call every time. Resolving usernames is an expensive
operation and will start hitting flood waits around 50 usernames

Similar limits apply to invite links, and you should use their

Turns the given entity into its input entity version.
Most requests use this kind of :tl:`InputPeer`, so this is the most
suitable call to make for those cases. **Generally you should let the
library do its job** and don't worry about getting the input entity
first, but if you're going to use an entity often, consider making the
call:
Arguments
entity (`str` | `int` | :tl:`Peer` | :tl:`InputPeer`):
If a username or invite link is given, **the library will
use the cache**. This means that it's possible to be using
a username that *changed* or an old invite link (this only
happens if an invite link for a small group chat is used
after it was upgraded to a mega-group).
If the username or ID from the invite link is not found in
the cache, it will be fetched. The same rules apply to phone
numbers (``'+34 123456789'``) from people in your contact list.
If an exact name is given, it must be in the cache too. This
is not reliable as different people can share the same name
and which entity is returned is arbitrary, and should be used
only for quick tests.
If a positive integer ID is given, the entity will be searched
in cached users, chats or channels, without making any call.
If a negative integer ID is given, the entity will be searched
exactly as either a chat (prefixed with ``-``) or as a channel
(prefixed with ``-100``).
If a :tl:`Peer` is given, it will be searched exactly in the
cache as either a user, chat or channel.
If the given object can be turned into an input entity directly,
said operation will be done.
Unsupported types will raise ``TypeError``.
If the entity can't be found, ``ValueError`` will be raised.
Returns
