Closes #3936. There are two changes made to ensure the first update in a channel cannot be lost, first by always sorting updates before applying pts, and second by cautiously initializing the local pts if the client had no pts known beforehand. It might be possible to cleanup the handling of possible gaps now that updates are always sorted, but that requires more thought.
Telethon
========
.. epigraph::
⭐️ Thanks **everyone** who has starred the project, it means a lot!
|logo| **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.
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
----------
.. code-block:: sh
pip3 install telethon
Creating a client
-----------------
.. code-block:: python
from telethon 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
-----------
.. code-block:: 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!')
