python 中的 Telethon 機器人中的 aiter 錯誤

Question

我正在嘗試為我的機器人在我的異步 function 中循環，對於自動銷毀 function 我必須迭代所有用戶並檢查用戶是否是管理員，使用以下代碼完成：

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

當我嘗試運行我的代碼時出現問題，返回此錯誤

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

有什么解決辦法嗎？

Answer 1

get_participants返回一個列表，而不是異步迭代器：

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

但是，這仍然行不通，因為user和admins對象可能不同。 您應該通過比較id來查找admins ，而不是整個user object。
