Turns the given entity into a valid Telegram :tl:`User`, :tl:`Chat`

and they will be efficiently fetched from the network.
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
in a short period of time.
If you want to get the entity for a *cached* username, you should
first `get_input_entity(username) <get_input_entity>` which will
use the cache), and then use `get_entity` with the result of the
previous call.
Similar limits apply to invite links, and you should use their
ID instead.
Using phone numbers (from people in your contact list), exact
names, integer IDs or :tl:`Peer` rely on a `get_input_entity`
first, which in turn needs the entity to be in cache, unless
a :tl:`InputPeer` was passed.
Unsupported types will raise ``TypeError``.
If the entity can't be found, ``ValueError`` will be raised.
Returns
:tl:`User`, :tl:`Chat` or :tl:`Channel` corresponding to the
input entity. A list will be returned if more than one was given.

"""
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
:tl:`InputPeerUser`, :tl:`InputPeerChat` or :tl:`InputPeerChannel`
or :tl:`InputPeerSelf` if the parameter is ``'me'`` or ``'self'``.
If you need to get the ID of yourself, you should use
`get_me` with ``input_peer=True``) instead.
Example
.. code-block:: python
# If you're going to use "username" often in your code
# (make a lot of calls), consider getting its input entity
# once, and then using the "user" everywhere instead.
