- Level 3 complete (you understand packages, error handling, project structure)
- Comfortable with functions and classes
- How
asyncandawaitwork under the hood - Running concurrent tasks with
asyncio - Making concurrent HTTP requests with
aiohttp - Async generators and file processing
- Producer-consumer patterns with
asyncio.Queue
Normal Python runs one thing at a time. When your code waits for a network response or a file read, it just sits there doing nothing. Async lets your code do other work while waiting. This is essential for web servers, scrapers, and anything that talks to external systems.
