What is python-telegram-bot?

python-telegram-bot lets you build a chatbot for Telegram using Python. Instead of wrestling with Telegram's raw API, you get a set of friendly building blocks that handle the plumbing, receiving messages, sending replies, and managing the back-and-forth between a user and your bot. At its core, the library wraps the Telegram Bot API so you don't have to. It exposes all of Telegram's supported message types and methods as simple Python objects and functions. On top of that raw interface, it includes higher-level helper classes (in a submodule called telegram.ext) that make common bot patterns straightforward, things like listening for specific commands, filtering messages, or keeping track of conversation state. You write Python, and the library talks to Telegram for you. Anyone who wants to create a Telegram bot would use this. That could be a startup building a customer support bot that answers FAQs in a group chat, a PM prototyping a notification service that pings users when a delivery status changes, or a hobbyist making a bot that echoes back messages or posts daily reminders. The project ships a set of example bots you can copy and modify, including one called echobot2 that the maintainers describe as the starting point for most bots in the wild. The library supports a wide range of Python versions and even works on Google App Engine, so it's flexible about where you deploy. The project is actively maintained with a community available on Telegram, Stack Overflow, and IRC for support. It's licensed under LGPL-3, which means you can use it in your own applications without those applications being forced into the same license, only modifications to the library itself need to stay under LGPL.
