aiotg

Asynchronous Python API for building Telegram bots, featuring:

Install it with pip:

.. code:: sh

pip install aiotg

Then you can create a new bot in few lines:

.. code:: python

from aiotg import Bot, Chat

bot = Bot(api_token="...")

@bot.command(r"/echo (.+)")
def echo(chat: Chat, match):
    return chat.reply(match.group(1))

bot.run()

Now run it with a proper API_TOKEN and it should reply to /echo commands.

.. note:: Type annotations are not required but will help your editor/IDE to provide code completion.

The example above looks like a normal synchronous code but it actually returns a coroutine. If you want to make an external request (and that's what bots usually do) just use aiohttp and async/await syntax:

.. code:: python

import aiohttp
from aiotg import Bot, Chat

bot = Bot(api_token="...")

@bot.command("bitcoin")
async def bitcoin(chat: Chat, match):
    url = "https://apiv2.bitcoinaverage.com/indices/global/ticker/BTCUSD"
    async with aiohttp.ClientSession() as session:
        response = await session.get(url)
        info = await response.json()
        await chat.send_text(str(info["averages"]["day"]))

bot.run()

But what if you just want to write a quick integration and don't need to provide a conversational interface? We've got you covered! You can send messages (or any other media) by constructing a Chat object with user_id or channel name. We even saved you some extra keystrokes by providing handy Channel constructors:

.. code:: python

...
channel = bot.channel("@yourchannel")
private = bot.private("1111111")

async def greeter():
    await channel.send_text("Hello from channel!")
    await private.send_text("Why not greet personally?")
...
