Telegram Get All Group Members with Telethon
In the previous post, we obtained the list of IDs of active group members by querying the most recent 1000 messages in a group.
When ChannelParticipantsBanned is used as a filter, calling the client.iter_participants() function returns such users:
If I want to be especially kind to the members of this group, as long as they are currently in the group, I don't want any of them to be disturbed by bots.
Then I need to get all the members within the group.
Developed with GPT.
Don't forget, we just finished the project for querying recent messages in a group. For ease of reading and learning, copy and paste all the code from the previous project, and add the following requirements. Send it to GPT.
Query all members in a telegram group
Output format is yaml
telegram account userid: uesrname: telegram account username
full_name: telegram account full name
For example
6611601789:
username: skypatch
full_name: 蛙 女
This group may be a public group or a non-public group
After some simple debugging, the code ran normally. But the users obtained included users in the exceptions. This is not what we want; the user list we want should also exclude this portion of users.
This step took a relatively long time to figure out, and the results returned by GPT had issues.
I used Claude, Gemini, and ChatGPT at the same time.
Combined with the official Telethon documentation. Finally got it done.

Postscript
In Telethon, both ChannelParticipantBanned and ChannelParticipantsBanned are "things" that are valid.
After import, you can use
from telethon.tl.types import ChannelParticipantBanned, ChannelParticipantsBanned
ChannelParticipantsBanned
is a filter, used as a parameter for the client.iter_participants() function
See the official documentation
Exceptions in the group's Permissions
ChannelParticipantBanned
is a possible value of a user's "attribute" participant, used to determine whether the user is in this list:
Exceptions in the group's Permissions (see image above)
The usage is like this:
isinstance(user.participant, ChannelParticipantBanned)
What needs to be noted is
Both of these "things" are called *****Banned. But actually, Exceptions means a setting that takes priority over the group's default permission settings.
For example, in my group, the default user permission does not allow sending stickers. However, a certain user can be set in Exceptions to be able to send stickers. Do you think this counts as "Banned"?
