# Python Async/Await Guide
## Async Basics
- Use async def for coroutines
- await async functions
- Create tasks with asyncio.create_task
- Use asyncio.gather for concurrency
## FastAPI Async
- Define async route handlers
- Use async database operations
- Implement background tasks
- Handle WebSocket connections
## Database Operations
- Use async drivers (asyncpg, motor)
- Implement connection pooling
- Handle transactions properly
- Use async context managers
## Best Practices
- Don't block the event loop
- Use asyncio.run() as entry point
- Handle cancellation properly
- Implement proper error handling
