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 ``echobot2``, it is the de facto base for most of the bots out there. Best of all,
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.

# Examples
In this folder are small examples to show what a bot written with `python-telegram-bot` looks like. Some bots focus on one specific aspect of the Telegram Bot API while others focus on one of the mechanics of this library. Except for the [`echobot.py`](#pure-api) example, they all use the high-level framework this library provides with the [`telegram.ext`](https://python-telegram-bot.readthedocs.io/en/latest/telegram.ext.html) submodule.

This is probably the base for most of the bots made with `python-telegram-bot`. It simply replies to each text message with a message that contains the same text.
