Quick Answer
concurrent.futures provides a high-level interface for parallel tasks. ThreadPoolExecutor for I/O-bound parallel tasks. ProcessPoolExecutor for CPU-bound parallel tasks (bypasses GIL with separate processes). Submit tasks with executor.submit(fn, args) returns Future. executor.map(fn, iterable) for parallel map. Use with context manager: with ThreadPoolExecutor(max_workers=4) as executor:.
Answer
Use ThreadPoolExecutor or ProcessPoolExecutor. submit() runs tasks asynchronously. Retrieve results using result() or as_completed().
