threading vs asyncio in python

Comments(1)

In Python, threading and asyncio are two different ways of achieving concurrency, which is the ability to run multiple tasks concurrently within a single program.

threading is a built-in Python module that provides support for creating and managing threads. A thread is a separate flow of execution within a program, and multiple threads can be run concurrently, allowing your program to perform multiple tasks at the same time. threading is a good choice for tasks that are CPU-bound, meaning they spend a lot of time performing calculations, because it can take advantage of multiple CPU cores to perform the calculations in parallel. However, threading is not well-suited for tasks that are I/O-bound, meaning they spend a lot of time waiting for external resources such as network connections or file access. This is because threading can only run one thread at a time, so if one thread is blocked waiting for I/O, the other threads will be unable to run.

asyncio, on the other hand, is a Python library for writing asynchronous code using the async/await syntax introduced in Python 3.5. Asynchronous code is designed to allow your program to perform I/O-bound and high-level structured network code without the need for multi-threading. asyncio uses an event loop to schedule tasks and manage their execution, allowing your program to perform multiple tasks concurrently while using a single thread. This can be more efficient than using threading, because it allows you to avoid the overhead of managing multiple threads. asyncio is particularly useful for tasks that involve a lot of waiting, such as those that involve making network requests or interacting with databases.

In general, threading is a good choice for tasks that are CPU-bound, while asyncio is a good choice for tasks that are I/O-bound or involve high-level network programming. It's also worth noting that asyncio is built on top of threading, so if you need to use both threading and asyncio in the same program, you can do so by running the asyncio event loop in a separate thread.
