 Telethon is an [asyncio](https://docs.python.org/3/library/asyncio.html) Python 3 [MTProto](https://core.telegram.org/mtproto) library to interact with [Telegram](https://telegram.org)'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](https://docs.telethon.dev/en/stable/misc/compatibility-and-convenience.html) to learn how to migrate. As with any third-party library for Telegram, be careful not to break [Telegram's ToS](https://core.telegram.org/api/terms) or [Telegram can ban the account](https://docs.telethon.dev/en/stable/quick-references/faq.html#my-account-was-deleted-limited-when-using-the-library).
## 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.
## Installing
`sh
pip3 install heroku-tl-new
`
## Creating a client
```python from herokutl import TelegramClient, events, sync
# 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
```python 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!')
