Telethon: Same entity type for a group and channel in telethon
问题
我有一堆句柄（@xyz），我试图找出该句柄属于用户、组还是频道。为了检查它，我正在尝试以下代码：
from telethon.sync import TelegramClient
from telethon.tl.types import Channel, Chat, User
async def check_handle(client,handle):
username = handle
try:
entity = await client.get_entity(username)
if entity:
if isinstance(entity, User): # 检查是否为用户（私聊）
print(f"{username} 是一个私聊。")
elif isinstance(entity, Channel): # 检查是否为频道
print(f"{username} 是一个频道。")
elif isinstance(entity, Chat): # 检查是否为聊天组
print(f"{username} 是一个群组。")
else:
print(f"无法确定 {username} 的类型。")
except ValueError as e:
print(f"错误：{e}")
await check_handle(client,'@aim4pg') # 调用该函数。
上述代码返回 - "@aim4pg 是一个频道"，但我可以清楚地在Telegram中搜索到所提到的句柄是一个具有X个成员的群组。
我有点知道为什么会发生这种情况 - 频道和群组都返回Channel实体（我尝试过一个频道和一个群组进行实验）。如果是用户，它返回User实体。
需要帮助：如何在Telethon中确定它是群组、频道还是用户？
英文:
I have a bunch of handles(@xyz) and I am trying to find if that handle belongs to a user, a group or a channel. To check it, I am trying with the below code:
from telethon.sync import TelegramClient
from telethon.tl.types import Channel, Chat, User
async def check_handle(client,handle):
username = handle
try:
entity = await client.get_entity(username)
if entity:
if isinstance(entity, User): # Check if it's a User (private chat)
print(f"{username} is a private chat.")
elif isinstance(entity, Channel): # Check if it's a Channel
print(f"{username} is a channel.")
elif isinstance(entity, Chat): # Check if it's a Chat (group)
print(f"{username} is a group.")
else:
print(f"Unable to determine the type of {username}.")
except ValueError as e:
print(f"Error: {e}")
........
........
await check_handle(client,'@aim4pg') # Call to the function.
The above code returns - "@aim4pg is a channel.", but I can clearly see on searching telegram that the mentioned handle is a group with X numbers of members in it.
I kind of know why it is happening - Both channel as well as group return Channel entity(I tried to experiment with one channel and one group). And if it is a user, it returns User entity.
Help needed: How to determine if it is a group or channel or user in Telethon?

"Megagroups" 是 Channels，其中 megagroup 设置为 True：https://tl.telethon.dev/constructors/channel.html

Megagroups are Channels with megagroup set to True: https://tl.telethon.dev/constructors/channel.html

在Telegram中，只有三种聊天类型：
- 用户（可以设置.bot标志）
- 频道（只能设置.megagroup或.broadcast标志中的一个）
- 聊天（小群组，它们不能设置用户名）
通过get_entity函数返回的内容不会有其他类型。
通常情况下，非小群组在API中称为“megagroup”，它们的类型也是Channel，并具有类似的行为。频道被称为广播。
要区分它们：
if isinstance(entity, Channel)
if entity.megagroup: # （也就是说，如果不是entity.broadcast）
# 这是一个超级群组
else:
# 这是一个广播频道
英文:
There are only three chat types in Telegram:
- User (can have .bot flag set)
- Channel (can have only one of the .megagroup or .broadcast flags set)
- Chat (small groups, they can have no username)
There can't be any other thing returned by get_entity.
The usual non-small groups are called "megagroup" in the api, they're also Channel in type and have similar behavior. channel is called broadcast.
to differentiate them:
if isinstance(entity, Channel)
if entity.megagroup: # (aka, if not entity.broadcast
# it's a supergroup
else:
# it's a broadcast channel
