An introduction to async programming - Writing a Telegram Antispam Bot in Python
summary
Quick intro to async concepts (event loop, coroutines, async/await, asyncio.create_task and asyncio.sleep) followed by a concrete Telegram antispam bot built with Pyrogram and released at https://github.com/eGenix/egenix-telegram-antispam-bot. Bot runs in production since April, bans 390 spam sign-ups from a ~150-member group, saves an estimated ~13 hours of manual moderation, uses async I/O with fallbacks to threads for blocking libraries, and demonstrably works.
