Kicking yourself (``'me'``) will result in leaving the chat. .. note:: Attempting to kick someone who was banned will remove their restrictions (and thus unbanning them), since kicking is just ban + unban. Arguments entity (`entity`): The channel or chat where the user should be kicked from. user (`entity`, optional): The user to kick. Example .. code-block:: python # Kick some user from some chat await client.kick_participant(chat, user) # Leaving chat await client.kick_participant(chat, 'me') """ entity = await self.get_input_entity(entity) user = await self.get_input_entity(user) if helpers._entity_type(user) != helpers._EntityType.USER: raise ValueError('You must pass a user entity') ty = helpers._entity_type(entity) if ty == helpers._EntityType.CHAT: await self(functions.messages.DeleteChatUserRequest(entity.chat_id, user)) elif ty == helpers._EntityType.CHANNEL: if isinstance(user, types.InputPeerSelf): await self(functions.channels.LeaveChannelRequest(entity)) else: await self(functions.channels.EditBannedRequest( channel=entity, user_id=user, banned_rights=types.ChatBannedRights(until_date=None, view_messages=True) )) await asyncio.sleep(0.5) await self(functions.channels.EditBannedRequest( channel=entity, user_id=user, banned_rights=types.ChatBannedRights(until_date=None) )) else: raise ValueError('You must pass either a channel or a chat') async def get_stats( self: 'TelegramClient', entity: 'hints.EntityLike', ): """ Retrieves statistics from the given megagroup or broadcast channel.
