|

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.
