Introduction

This library provides a pure Python interface for the Telegram Bot API. It's compatible with Python versions 3.6.8+. PTB might also work on PyPy, though there have been a lot of issues before. Hence, PyPy is not officially supported.

In addition to the pure API implementation, this library features a number of high-level classes to make the development of bots easy and straightforward. These classes are contained in the telegram.ext submodule.

A pure API implementation without telegram.ext is available as the standalone package python-telegram-bot-raw. See here for details.

Note

Installing both python-telegram-bot and python-telegram-bot-raw in conjunction will result in undesired side-effects, so only install one of both.

Telegram API support

All types and methods of the Telegram Bot API 5.3 are supported.

Installing

You can install or upgrade python-telegram-bot with:

$ pip install python-telegram-bot --upgrade

Or you can install from source with:

$ git clone https://github.com/python-telegram-bot/python-telegram-bot --recursive
$ cd python-telegram-bot
$ python setup.py install

In case you have a previously cloned local repository already, you should initialize the added urllib3 submodule before installing with:

$ git submodule update --init --recursive

Optional Dependencies

PTB can be installed with optional dependencies:

• pip install python-telegram-bot[passport] installs the cryptography library. Use this, if you want to use Telegram Passport related functionality.
• pip install python-telegram-bot[ujson] installs the ujson library. It will then be used for JSON de- & encoding, which can bring speed up compared to the standard json library.
• pip install python-telegram-bot[socks] installs the PySocks library. Use this, if you want to work behind a Socks5 server.

Getting started

Our Wiki contains a lot of resources to get you started with python-telegram-bot:

• Introduction to the API
• Tutorial: Your first Bot

Other references:

• Telegram API documentation
• python-telegram-bot documentation

Learning by example

We believe that the best way to learn this package is by example. Here are some examples for you to review. Even if it is not your approach for learning, please take a look at echobot.py, it is the de facto base for most of the bots out there. Best of all, the code for these examples are released to the public domain, so you can start by grabbing the code and building on top of it.

Visit this page to discover the official examples or look at the examples on the wiki to see other bots the community has built.

Logging

This library uses the logging module. To set up logging to standard output, put:

import logging
logging.basicConfig(level=logging.DEBUG,
                    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')

at the beginning of your script.

You can also use logs in your application by calling logging.getLogger() and setting the log level you want:

logger = logging.getLogger()
logger.setLevel(logging.INFO)

If you want DEBUG logs instead:

logger.setLevel(logging.DEBUG)

Documentation

python-telegram-bot's documentation lives at readthedocs.io.

Getting help

You can get help in several ways:

1. We have a vibrant community of developers helping each other in our Telegram group. Join us!
2. Report bugs, request new features or ask questions by creating an issue or a discussion.
3. Our Wiki pages offer a growing amount of resources.
4. You can even ask for help on Stack Overflow using the python-telegram-bot tag.

Contributing

Contributions of all sizes are welcome. Please review our contribution guidelines to get started. You can also help by reporting bugs.

Donating

Occasionally we are asked if we accept donations to support the development. While we appreciate the thought, maintaining PTB is our hobby and we have almost no running costs for it. We therefore have nothing set up to accept donations. If you still want to donate, we kindly ask you to donate to another open source project/initiative of your choice instead.
