Master async/await, event loops, and concurrency for I/O-bound, high-performance apps.

• Asynchronous programming with asyncio and async/await
• Non-blocking I/O operations using coroutines and tasks
• Concurrent execution of I/O-bound operations
• Async context managers and iterators for resource management

• Single-threaded cooperative multitasking via event loop
• Coroutines pause and resume using await
• Tasks run concurrently on the event loop
• Futures represent pending async results
• Async context managers auto-clean resources
• Async iterators support async for loops
• Error handling with return_exceptions=True
• Timeouts with asyncio.wait_for()

1. 1.Use async def for coroutines with await
2. 2.Use asyncio.gather() for concurrent execution
3. 3.Create tasks with asyncio.create_task()
4. 4.Handle errors with return_exceptions=True
5. 5.Use async with for resource cleanup
6. 6.Apply timeouts with asyncio.wait_for()
