Following these practices yields responsive, reliable applications.\n\n## Key findings\n- Use `asyncio.create_task()` (or `asyncio.ensure_future()`) to schedule coroutines as Tasks, allowing the event loop to monitor their state and enabling cancellation. [2]  \n- Replace blocking calls such as `time.sleep()` with `asyncio.sleep()` (or other async I/O) to keep the event loop responsive. [8]  \n- Run multiple independent coroutines concurrently with `asyncio.gather()` rather than awaiting them sequentially to achieve true parallelism. [8]  \n- Leverage `TaskGroup` (Python\u202f3.11+) for structured concurrency, which automatically cancels remaining tasks on error and ensures proper cleanup. [5]  \n- Explicitly close asynchronous generators or use context managers (e.g., `contextlib.aclosing`) to guarantee cleanup and avoid resource leaks. [7]  \n- Never create a Task and forget it; always await or handle its result to prevent unhandled exceptions.
