Demystifying Python's Async and Await Keywords

Рет қаралды 97,993

Күн бұрын

Python's async and parallel programming support is highly underrated. In this webinar, we introduce the entire spectrum of Python's parallel APIs. Then we focus in on the most promising, most useful, and modern feature of Python's async capabilities: the async and await keywords.
Repo used in this webinar: github.com/mikeckennedy/async...
During the webinar, we build a small application that interacts with web APIs using async and await. We close it out by covering a library and technique that allows us to join Python's disparate parallel APIs into one super API that is easier to work with.
About the Presenter:

This is great tutorial! It really helped me to understand asyncio better. I would like to have some kind of example for protocols and transporting data (as this is the use case I would like to use asyncio for), so I would be greatful if you could add some additional video or share some other training materials in the topic.

Thanks for the great video! I’m a big fan of your podcast content. I’m looking to use asyncio as a way of testing for my discord bot using pytest-asyncio so that my bot can stay running during testing while running some of its functions. I don’t want it to shut down or get hung up on a single function but would rather it run concurrently (a new term I learned 😁) so that I can attempt to test lets say maybe 4 or 5 functions all at the same time while the bot is “live”. That’s my use case so that I can push out more features without having to turn the bot on and off for each and every feature. I just want the bot to stay ON and run tests.

I have never seen an arrow character in python code or in any coding language for that matter. Can you explain how you even got it to show up in the text as well as what function it is performing here?

It's ->, a return type annotation. See mypy and PEP 484.

Very nice intro to python-async. One question, is unsync production ready or is it more experimental ?

@mikeckennedy 4 жыл бұрын

Hi, I think unsync is production ready. If you look at what it does, it's just a wrapper / cleanup on top of asyncio's event loops. Seems solid enough.

You are mixing in terms like parallel and serial into the discussion about concurrent/asynchronous. That's confusing, because parallel is not the same as concurrent.

too much of "idk" and "maybe" for an expert in async programming also this "try except" failure... i think its just an anti ad for his courses overall it looks like that somebody didnt practice the topic enough so still waiting for a little better explanation than "async is good for io and you grab loop and you know, launch tasks" just another tutorial that scratches the surface, there are tons of that in the internet p.s. sorry, but it just so frustrating

@piby1802 5 жыл бұрын

What do you need to learn more besides that? And why? Especially when he introduced unsync. Sorry but that's all you need to know unless you need to do something bizarre
