entity (`entity`):

The entity from which to retrieve the participants list.

limit (`int`):

Limits amount of participants fetched.
|

search (`str`, optional):

Look for participants with this string in name/username.

If ``aggressive is True``, the symbols from this string will

be used.

filter (:tl:`ChannelParticipantsFilter`, optional):
|
|
The filter to be used, if you want e.g. only admins
|
|
Note that you might not have permissions for some filter.
|
|
This has no effect for normal chats or users.
|
|
|
|
.. note::
|
|
|
|
The filter :tl:`ChannelParticipantsBanned` will return
|
|
*restricted* users. If you want *banned* users you should
|
|
use :tl:`ChannelParticipantsKicked` instead.
|
|
|
|
aggressive (`bool`, optional):
|
|
Aggressively looks for all participants in the chat.
|
|
|
|
This is useful for channels since 20 July 2018,
|
|
Telegram added a server-side limit where only the
|
|
first 200 members can be retrieved. With this flag
|
|
set, more than 200 will be often be retrieved.
|
|
|
|
This has no effect if a ``filter`` is given.

|
|
_total (`list`, optional):
|
|
A single-item list to pass the total parameter by reference.
|
|
|
|
Yields:
|
|
The :tl:`User` objects returned by :tl:`GetParticipantsRequest`
|
|
with an additional ``.participant`` attribute which is the
|
|
matched :tl:`ChannelParticipant` type for channels/megagroups

or :tl:`ChatParticipants` for normal chats.
