Master asynchronous Python event loops, avoid blocking code traps, and handle concurrent tasks. ## Steps 1. Understand that Python asyncio runs on a single-threaded event loop. 2. Never call synchronous blocking functions (like time.sleep() or requests.get()) inside async def functions. 3. Use non-blocking equivalents: asyncio.sleep() and aiohttp / httpx for HTTP requests. 4. Use asyncio.gather() to execute multiple independent async API calls concurrently. 5. If synchronous CPU-heavy work is unavoidable, offload it using loop.run_in_executor(). 6. Verify async loop health by ensuring event loop latency stays under 10ms. ## Notes - Calling time.sleep(5) inside an async function completely freezes all other tasks running on that Python event loop. - httpx provides an intuitive async HTTP client library API similar to requests.
