Pf moore Paul Moore May 8 2021 10 06am 1 I have a frustrating problem I m writing an application that downloads files unzips them and extracts a single file from the archive I want to use asyncio to manage the downloading See below for the background on why I m using asyncio but for now let s take asyncio as given Wrapping async functions for use in sync code Discussions on Python. There are four cases Calling sync code from sync code This is just a normal function call like time sleep 10 Nothing risky or special about this Calling async code from async code You have to use await here so you would do await asyncio sleep 10 Calling sync code from async code For example we can make an asynchronous function call This will issue the re to make the function call and will not wait around for the call to complete Running async functions in Python with asyncio run What is the Event Loop Non blocking IO is a way of performing IO where reads and writes are reed although performed
