============
Introduction
============

This library provides a pure Python interface for the
`Telegram Bot API <https://core.telegram.org/bots/api>`_.
It's compatible with Python versions **3.7+**. PTB might also work on `PyPy <http://pypy.org/>`_, 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. <https://github.com/python-telegram-bot/python-telegram-bot/blob/master/README_RAW.rst>`_

----
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 **6.0** are supported.

===========
Concurrency
===========

Since v14.0, ``python-telegram-bot`` is built on top of Pythons ``asyncio`` module.
Because ``asyncio`` is in general single-threaded, ``python-telegram-bot`` does currently not aim to be thread-safe.
Noteworthy parts of ``python-telegram-bots`` API that are likely to cause issues (e.g. race conditions) when used in a multi-threaded setting include:

* ``telegram.ext.Application/Updater.update_queue``
* ``telegram.ext.ConversationHandler.check/handle_update``
* ``telegram.ext.CallbackDataCache``
* ``telegram.ext.BasePersistence``
* all classes in the ``telegram.ext.filters`` module that allow to add/remove allowed users/chats at runtime

==========
Installing
==========

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

.. code:: shell

    $ pip install python-telegram-bot --upgrade

Or you can install from source with:

.. code:: shell

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

-----------------------------
Dependencies & Their Versions
-----------------------------

``python-telegram-bot`` tries to use as few 3rd party dependencies as possible.
However, for some features using a 3rd party library is more sane than implementing the functionality again.
The dependencies are:

* `httpx ~= 0.22.0 <https://www.python-httpx.org>`_ for ``telegram.request.HTTPXRequest``, the default networking backend
* `tornado~=6.1 <https://www.tornadoweb.org/en/stable/>`_ for ``telegram.ext.Updater.start_webhook``
* `cachetools~=5.0.0 <https://cachetools.readthedocs.io/en/latest/>`_ for ``telegram.ext.CallbackDataCache``
* `APScheduler~=3.9.1 <https://apscheduler.readthedocs.io/en/3.x/>`_ for ``telegram.ext.JobQueue``

``python-telegram-bot`` is most useful when used along with additional libraries.
To minimize dependency conflicts, we try to be liberal in terms of version requirements on the dependencies.
On the other hand, we have to ensure stability of ``python-telegram-bot``, which is why we do apply version bounds.
If you encounter dependency conflicts due to these bounds, feel free to reach out.

---------------------
Optional Dependencies
---------------------

PTB can be installed with optional dependencies:

* ``pip install python-telegram-bot[passport]`` installs the `cryptography>=3.0 <https://cryptography.io>`_ library. Use this, if you want to use Telegram Passport related functionality.
* ``pip install python-telegram-bot[json]`` installs the `ujson>=4.0.0 <https://pypi.org/project/ujson/>`_ library. It will then be used for JSON de- & encoding, which can bring speed up compared to the standard `json <https://docs.python.org/3/library/json.html>`_ library.
* ``pip install python-telegram-bot[socks]`` installs ``httpx[socks]``. 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 <https://github.com/python-telegram-bot/python-telegram-bot/wiki/Introduction-to-the-API>`_
- Tutorial: `Your first Bot <https://github.com/python-telegram-bot/python-telegram-bot/wiki/Extensions-%E2%80%93-Your-first-Bot>`_

- `python-telegram-bot documentation <https://python-telegram-bot.readthedocs.io/>`_

-------------------
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 is released to the public domain, so you can start by grabbing the
code and building on top of it.

Visit `this page <https://github.com/python-telegram-bot/python-telegram-bot/blob/master/examples/README.md>`_ to discover the official examples or look at the examples on the `wiki <https://github.com/python-telegram-bot/python-telegram-bot/wiki/Examples>`_ to see other bots the community has built.

-------
Logging
-------

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

.. code:: python

    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:

.. code:: python

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

If you want DEBUG logs instead:

.. code:: python

    logger.setLevel(logging.DEBUG)

========
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.
