"""Get the InputPeer of a known peer id.
Useful whenever an InputPeer type is required.
.. note::
This is a utility method intended to be used **only** when working with raw
:obj:`functions <hydrogram.api.functions>` (i.e: a Telegram API method you wish to use which is not
available yet in the Client class as an easy-to-use method).
.. include:: /_includes/usable-by/users-bots.rst
Parameters:
peer_id (``int`` | ``str``):
The peer id you want to extract the InputPeer from.
Can be a direct id (int), a username (str) or a phone number (str).
Returns:
``InputPeer``: On success, the resolved peer id is returned in form of an InputPeer object.
Raises:
KeyError: In case the peer doesn't exist in the internal database.
