asyncio

Asyncio provides infrastructure for writing single-threaded concurrent code. It uses coroutines, which are special functions that can suspend and resume execution, allowing other tasks to run while waiting for I/O operations (like network requests or file reads) to complete. This avoids blocking the main thread, leading to more responsive and efficient programs, especially in scenarios involving many asynchronous operations like web servers, event loops, and concurrent data processing. Asyncio’s core components include event loops, coroutines, tasks, and futures, which work together to manage and execute asynchronous code. It’s particularly useful for I/O-bound applications where waiting on external resources is a significant factor.
