I’m trying to use asyncio in my Python program but it keeps failing with ImportError: No module named asyncio. asyncio is supposed to be a built-in library so why is this failing?

Here’s some example code I was able to reproduce it on:

import asyncio

async def main():


You’re write, asyncio is a built-in library for Python versions 3.7+. So if you’re getting an error with the import, check your python version with python --version and make sure that you’re running at least version 3.7.

did this help?
