python 中的 Telethon 机器人中的 aiter 错误

Question

i'm trying to loop inside my async function for my bot, and for the autodestruction function i have to iterate all the users and check if the user is an admin, done with this code:

all_participants = await bot.get_participants(group, aggressive=False)
    admins = bot.iter_participants(group, filter=ChannelParticipantsAdmins)
    print('[+] Banno gli utenti...')
    async for user in all_participants:
        if not user in admins:
            pass

The issue comes when i try to run my code, returning this error

Traceback (most recent call last):
  File "/home/elias/.local/lib/python3.8/site-packages/telethon/client/updates.py", line 467, in _dispatch_update
    await callback(event)
  File "bannerbot.py", line 31, in pyro
    async for user in all_participants:
TypeError: 'async for' requires an object with __aiter__ method, got TotalList

Any solutions?

Answer 1

get_participants returns a list, not an async iterator:

all_participants = await bot.get_participants(group, aggressive=False)
admins = await bot.get_participants(group, filter=ChannelParticipantsAdmins)
#                  ^^^ get, not iter
print('[+] Banno gli utenti...')
for user in all_participants:
# ^ removed the async
    if not user in admins:
        pass

However this still won't work because the user and admins objects are probably different. You should look for admins by comparing the id , not the entire user object.
