Asyncio

Python’s asyncio module provides infrastructure for writing single-threaded concurrent code using coroutines, multiplexing I/O access over sockets and other resources, running network clients and servers, and other related primitives. Unlike threading, asyncio uses cooperative multitasking, where tasks voluntarily yield control to allow other tasks to run. This makes it ideal for I/O-bound applications like web servers, database clients, and network services where waiting for external resources is the primary bottleneck.

This section covers asyncio from basic concepts to advanced patterns, including the event loop, coroutines, tasks, synchronization primitives, and real-world examples like TCP/UDP servers, HTTP clients, and connection pools.
