Arguments

limit (`int` | `None`):

How many dialogs to be retrieved as maximum. Can be set to

`None` to retrieve all dialogs. Note that this may take

offset_peer (:tl:`InputPeer`, optional):

Whether pinned dialogs should be ignored or not.

When set to `True`, these won't be yielded at all.

ignore_migrated (`bool`, optional):

Whether :tl:`Chat` that have ``migrated_to`` a :tl:`Channel`
|
|

|
dialogs are returned, but setting this to `True` will ignore

|

The folder from which the dialogs should be retrieved.

If set to a folder number like ``1``, only those from

By default Telegram assigns the folder ID ``1`` to

archived chats, so you should use that if you need

archived (`bool`, optional):

Creates a `Conversation <telethon.tl.custom.conversation.Conversation>`

.. note::
|
|
|
|
This Conversation API has certain shortcomings, such as lacking
|
|
persistence, poor interaction with other event handlers, and
|
|
overcomplicated usage for anything beyond the simplest case.
|
|
|
|
If you plan to interact with a bot without handlers, this works

fine, but when running a bot yourself, you may instead prefer
|
|
to follow the advice from https://stackoverflow.com/a/62246569/.
|
|
|
|
This is not the same as just sending a message to create a "dialog"
|
|
with them, but rather a way to easily send messages and await for
|
|
responses or other reactions. Refer to its documentation for more.

|
Arguments
|
|
entity (`entity`):

|
The entity with which a new conversation should be opened.

|
The default timeout (in seconds) *per action* to be used. You
|
|
may also override this timeout on a per-method basis. By
|
|
default each action can take up to 60 seconds (the value of
|
|
this timeout).
|
|
|
|
total_timeout (`int` | `float`, optional):
|
|
The total timeout (in seconds) to use for the whole
|
|
conversation. This takes priority over per-action
|
|
timeouts. After these many seconds pass, subsequent
|
|
actions will result in ``asyncio.TimeoutError``.
|
|
|
|
max_messages (`int`, optional):
|
|
The maximum amount of messages this conversation will
|
|
remember. After these many messages arrive in the
|
|
specified chat, subsequent actions will result in
|
|
``ValueError``.
|
|
|
|
exclusive (`bool`, optional):
|
|
By default, conversations are exclusive within a single
|
|
chat. That means that while a conversation is open in a
|
|
chat, you can't open another one in the same chat, unless
|
|
you disable this flag.
|
|
|
|
If you try opening an exclusive conversation for
|
|
a chat where it's already open, it will raise
|
|
``AlreadyInConversationError``.
|
|
|
|
replies_are_responses (`bool`, optional):
|
|
Whether replies should be treated as responses or not.
|
|
|
|
If the setting is enabled, calls to `conv.get_response
|
|
<telethon.tl.custom.conversation.Conversation.get_response>`
|
|
and a subsequent call to `conv.get_reply
|
|
<telethon.tl.custom.conversation.Conversation.get_reply>`
|
|
will return different messages, otherwise they may return

|
the same message.

Consider the following scenario with one outgoing message,
|
|
1, and two incoming messages, the second one replying::
|
|
|
|
Hello! <1
|
|
2> (reply to 1) Hi!
|
|
3> (reply to 1) How are you?
|
|
|
|
And the following code:
|
|
|
|
.. code-block:: python
|
|
|
|
async with client.conversation(chat) as conv:
|
|
msg1 = await conv.send_message('Hello!')
|
|
msg2 = await conv.get_response()
|
|
msg3 = await conv.get_reply()
|
|
|
|
With the setting enabled, ``msg2`` will be ``'Hi!'`` and
|
|
``msg3`` be ``'How are you?'`` since replies are also
|
|
responses, and a response was already returned.
|
|
|
|
With the setting disabled, both ``msg2`` and ``msg3`` will
|
|
be ``'Hi!'`` since one is a response and also a reply.
|
|
|
|
Returns
|
|
A `Conversation <telethon.tl.custom.conversation.Conversation>`.
|
|
|
|
Example
|
|
.. code-block:: python
|
|
|
|
# <you> denotes outgoing messages you sent
|
|
# <usr> denotes incoming response messages
|
|
with bot.conversation(chat) as conv:
|
|
# <you> Hi!
|
|
conv.send_message('Hi!')
|
|
|
|
# <usr> Hello!
|
|
hello = conv.get_response()
|
|
|
|
# <you> Please tell me your name
|
|
conv.send_message('Please tell me your name')
|
|
|
|
# <usr> ?
|
|
name = conv.get_response().raw_text
|
|
|
|
while not any(x.isalpha() for x in name):
|
|
# <you> Your name didn't have any letters! Try again
|
|
conv.send_message("Your name didn't have any letters! Try again")
|
|
|
|
# <usr> Human
|
|
name = conv.get_response().raw_text
|
|
|
|
# <you> Thanks Human!
|
|
conv.send_message('Thanks {}!'.format(name))
