"""Iterate through the members of a chat sequentially.
This convenience method does the same as repeatedly calling :meth:`~pyrogram.Client.get_chat_members` in a loop,
thus saving you from the hassle of setting up boilerplate code. It is useful for getting the whole members list
of a chat with a single call.
Parameters:
chat_id (``int`` | ``str``):
Unique identifier (int) or username (str) of the target chat.
limit (``int``, *optional*):
Limits the number of members to be retrieved.
query (``str``, *optional*):
Query string to filter members based on their display names and usernames.
Defaults to "" (empty string).
A query string is applicable only for *"all"*, *"banned"* and *"restricted"* filters only.
filter (``str``, *optional*):
Filter used to select the kind of members you want to retrieve. Only applicable for supergroups
and channels. It can be any of the followings:
*"all"* - all kind of members,
*"banned"* - banned members only,
*"restricted"* - restricted members only,
*"bots"* - bots only,
*"recent"* - recent members only,
*"administrators"* - chat administrators only.
Defaults to *"recent"*.
Returns:
``Generator``: A generator yielding :obj:`~pyrogram.types.ChatMember` objects.
Example:
.. code-block:: python
# Iterate though all chat members
for member in app.iter_chat_members(chat_id):
print(member.user.first_name)
# Iterate though all administrators
for member in app.iter_chat_members(chat_id, filter="administrators"):
print(member.user.first_name)
# Iterate though all bots
for member in app.iter_chat_members(chat_id, filter="bots"):
print(member.user.first_name)
