Description

Asyncio is your choice for running multiple tasks concurrently such as network requests or reading files, without using much CPU power.

Nice explanation! I use semaphores for co-current web request to a client that has some throttling. I like how you explained it and the others which i didn't know about.

Really I've heard couple of asyncio tutorials but I have to say, this is the best. Thanks a lot

Great tutorial! Great depth while still being very accessible. Keep up the great work! Perhaps worth a mention for our Spyder brethren and sistren... the iPython console runs its own loop which can interfere with the asyncio code. If the iPython console throws errors when running asyncio code, (but the code runs just fine in terminal), the nest_asyncio package can be imported to improve compatibility in the iPython console.
