"""Iterate through a chat or a user profile photos sequentially.
|
|
|
|
This convenience method does the same as repeatedly calling :meth:`~Client.get_profile_photos` in a loop, thus
|
|
saving you from the hassle of setting up boilerplate code. It is useful for getting all the profile photos with
|
|
a single call.
|
|
|
|
Parameters:
|
|
chat_id (``int`` | ``str``):
|
|
Unique identifier (int) or username (str) of the target chat.
|
|
For your personal cloud (Saved Messages) you can simply use "me" or "self".
|
|
For a contact that exists in your Telegram address book you can use his phone number (str).
|
|
|
|
limit (``int``, *optional*):
|
|
Limits the number of profile photos to be retrieved.
|
|
By default, no limit is applied and all profile photos are returned.
|
|
|
|
offset (``int``, *optional*):
|
|
Sequential number of the first profile photo to be returned.
|
|
|
|
Returns:
|
|
``Generator``: A generator yielding :obj:`Photo` objects.
|
|
|
|
Example:
|
|
.. code-block:: python
|
|
|
|
for photo in app.iter_profile_photos("haskell"):
|
|
print(photo.file_id)
|
|
