Telethon

Telethon is an asyncio Python 3 MTProto library to interact with Telegram's API as a user or through a bot account (bot API alternative).

Important

If you have code using Telethon before its 1.0 version, you must read Compatibility and Convenience to learn how to migrate. As with any third-party library for Telegram, be careful not to break Telegram's ToS or Telegram can ban the account

What is this?

Telegram is a popular messaging application. This library is meant to make it easy for you to write Python programs that can interact with Telegram. Think of it as a wrapper that has already done the heavy job for you, so you can focus on developing an application.

What telethon-up does:3

⭐️The purpose of telethon-up is that it automatically updates the TL layer (api.tl) to the latest version of Telegram⭐️:3

Installing

pip3 install telethon-up

Creating a client

import telethon_up
from telethon import TelegramClient, events, sync
#import telethon
#print(f"Layer Start: {telethon.tl.alltlobjects.LAYER}")
telethon_up.check()
#print(f"Layer After: {telethon.tl.alltlobjects.LAYER}")
# Automatically update the Telethon API layer (api.tl).
# These example values won't work. You must get your own api_id and
# api_hash from https://my.telegram.org, under API Development.
api_id = 12345
api_hash = '0123456789abcdef0123456789abcdef'

client = TelegramClient('session_name', api_id, api_hash)
client.start()

Doing stuff

print(client.get_me().stringify())

client.send_message('username', 'Hello! Talking to you from Telethon')
client.send_file('username', '/home/myself/Pictures/holidays.jpg')

client.download_profile_photo('me')
messages = client.get_messages('username')
messages[0].download_media()

@client.on(events.NewMessage(pattern='(?i)hi|hello'))
async def handler(event):
  await event.respond('Hey!')
