An Introduction to Python Async IO

This article covers an Overview of Async IO in Python. Python 3's asyncio module provides fundamental tools for implementing asynchronous I/O in Python. It was introduced in Python 3.4, and with each subsequent minor release, the module has evolved significantly.

Asyncio is the standard library package with Python that aims to help you write asynchronous code by giving you an easy way to write, execute, and structure your coroutines. 

The Asyncio library is for concurrency, which is not to be confused with parallelism.

Concurrency does not mean Parallelism and vice-versa.

We can combine them both. 

We can have multiple threads, running Tasks parallely but each thread may not be running Tasks concurrently. 


1. Asynchronous IO (async IO): a language-agnostic paradigm (model) that has implementations across a host of programming languages.

2. async/await: two new Python keywords that are used to define coroutines.

3. asyncio: the Python package that provides a foundation and API for running and managing coroutines.
