Web11 jul. 2024 · What’s different to threading is that, asyncio is single-process and single-thread. There is an event loop in asyncio which routinely measure the progress of the tasks. If the event loop has measured any progress, it would schedule another task for execution, therefore, minimizing the time spent on waiting I/O. WebThere are two types of tasks. If a task doesn't carry out many calculations, but it does do a lot of input/output operations, it's called an I/O-bound task. Since CPU is much faster …
