python-telegram-bot

A pure Python, asynchronous interface for the Telegram Bot API, utilizing the `telegram.ext` module for high-level bot development.

This library delivers a pure Python, asynchronous interface for the official Telegram Bot API, compatible with Python 3.9+ environments. It goes beyond the raw API with high-level classes: specifically, the `telegram.ext` submodule provides the `Application` and various `Handler` classes (e.g., `CommandHandler`, `MessageHandler`) to streamline complex bot logic, message routing, and conversation flows. Developers use this structure to efficiently manage updates and build robust, scalable Telegram bots with minimal boilerplate code.
