如何使用 Telethon 获取传入电报消息的聊天或群组名称？

Question

I have this code

from telethon.sync import TelegramClient, events

with TelegramClient('name', api_id, api_hash) as client:
   @client.on(events.NewMessage(pattern=pattern))
   async def handler(event):
      await event.reply("Here should be the Chat or Group name")

How to implement this?

Answer 1

if we are talking only about groups/channels

chat_from = event.chat if event.chat else (await event.get_chat()) # telegram MAY not send the chat enity
chat_title = chat_from.title

Else (If we want to get the full name of chat entities, including Users):

from telethon import utils

chat_from = event.chat if event.chat else (await event.get_chat()) # telegram MAY not send the chat enity
chat_title = utils.get_display_name(chat_from)

get_display_name() actually gets a name that you would see. Works for types User, Channel, Chat That method shall not have await
