The asyncio.gather() function is useful for launching multiple coroutines concurrently and waiting for their results. It is commonly used for coordinating web requests, IO work, and parallel flows.

Concurrency and Thread Safety in Python's asyncio

Author: Mohan Ganesan

Date: Mar 17, 2024

Python's asyncio module enables concurrency within a single thread using an event loop. Sharing data between coroutines is thread-safe. Multithreading requires new event loops and explicit synchronization. Blocking code must execute in threads to avoid blocking the event loop. Following these best practices ensures efficient, thread-safe asyncio code.
