Ever wondered how asyncio works under the hood? Let’s break it down by building a lightweight asynchronous framework — from generators and coroutines to locks and an event loop. Perfect for understanding async Python deeply. 🧠✨

🔧 Key Concepts Covered:

  • Generators → Pause & resume execution (yield)
  • Coroutines → Declare async workflows with async/await
  • Event loop → Coordinates task execution
  • Locks → Ensure safe access to shared resources
  • sleep() → Custom delay without blocking the event loop

💡 Example Use Cases:

  • Simulating parallel email sending
  • Multiple robots writing to shared memory with locks
  • Tasks that yield execution to mimic async scheduling

🌀 Each generator task "yields" control so other tasks can run. It’s like a turn-based system for functions — smooth, efficient, and fun to build.

🎯 This isn’t just theory — it’s hands-on async architecture.

Mastering this builds true confidence in Python’s concurrency model.
