1:44 I think the point of 'await' is to let python do a context switch. Normal function call to sleep will also transfer control to the next line after the sleep is done, await doesn't affect that

Simple but most essential and elegant explanations for the asyncio. Huge thanks!

The `await asyncio.sleep(0.5)` isn't needed because "the task sometimes happends so fast that task.canceled is not going to be able to register the cancel in enough time"! But it's needed because `task.cancel()` doesn't actually start the cancelation but merely schedule it for cancellation. The task will be cancelled when control returns to the event loop, which happens when an await expression is encountered.

Awesome vid; glad I stumbled upon this! Much cleaner than threading/mp libraries, so I want to learn this one! Why does main have to be async def main and not just def main? Also, does that mean that any functions I use in the async module must have with the async keyword in the definition?

Thanks for this exposition 👍

11:10 the asyncio.sleep can be set to asyncio.sleep(0.0) and it will stil register i know its a bit late but still might be relevant..

thanks really understood the concept.

Great video, thanks!

Thanks for the content. I think there are a few ways to do this, In the example you execute the function and then append the returned data to the list, rather than appending the function call itself to a list, Here are 2 examples: tasks = [loop.create_task(kill_time(i)) for i in range(1, 10+1)] await asyncio.wait(tasks) for task in tasks: print(task.result()) or list_of = [] for i in range(1, 10+1): task = asyncio.create_task(kill_time(i)) list_of.append(task) await asyncio.gather(*list_of)

Very clear, thank you very much !

This was very helpful. Thank you.

Thanks o this video I've decided to rewrite my synchronous data grabber (web scrapping and directly via API) based on requests to asyncio and aiohttp. Speedup was about ~2x :)

Very clear 👌

Thanks for the explanation

I think this video is great. Very clear.

great tutorial!

For a noob like me this was awesome! Thank you

👏Clear and concise

are u using python 3.10?? bcs some function has depreced

Can I use this to constantly check if a program is running, then make an if statement saying if the program is not running open a file and if it’s already running print the name of the current file it’s running? I’m trying to make this but with a start and stop button…

Thanks for a simple explanation!

very nice

@7:15 isnt the function kill_time() already called before you do await.gather()

coroutines (any function with `yield` or `await` inside) should be `extracted` from a function first by a call syntax. But this call is not a call, it just returns a `coroutine` object.

doesnt await defeat the asynchronous behavior and make it blocking? 🤒

i think the explanation is wrong. Await starts a async coroutine, nothing to do with waiting afaik.

Nice explanation, very helpfull for me. A huge thanks !!

Your voice & accent sounds a lot like Naval Ravikant 😃

This is arguably the best asyncio-await explanation on youtube!. thanks for keeping it simple to understand!

Just follow along in practice. Not everything has to be a handout.

6:57 No. Use list_of_tasks = [kill_time(i) for i in range(1000)]

Why do you need list comprehension versus what he had?

11:15 I am strongly against waiting like that. I would loop or create something awaitable instead, but I want to learn it, and you giving me an anti-pattern like that makes me question the usefulness of the rest :/

You can be strongly against whatever you want. The sleep can also be set to 0 if you want, but you need to provide your script some context to be able to perform a switch or it never will.
