10:38 "the next important concept which is a task". But hang on, we supposedly just talked about tasks in the previous example... at least there were variables named task1 and task2. But maybe those were incorrectly named, and should have been called coroutine1 and 2? Because apparently (10:38) asyncio.create_task(coroutine) does something different, presumably returning something different than the task1 and task2 of the previous example. More red-herringly, having previously learned that executing a (coroutine? task?) requires awaiting it. Yet evidently in the (10:38) example, asyncio.create_task does not just create a task, it executes it (adds it to the event loop)... and the subsequent three awaits DON'T execute the tasks, but just wait for them to finish. Takeaways: "create_task()" should be named "create_and_execute_task()", and the "await" keyword should be named "run_if_not_running_then_await_with_some_yield_opportunities". It seems that the asyncio apparatus is not really all that complicated, but dang the asyncio landscape is riddled with unhelpfully-named features and concepts, and so many community explanations and examples that vaguely allude to how things work without managing to hit the target.

Hey Tim, just need a clarification on the usage of threads. Do they really work in 'parallel', especially in python? Cause I often here that GIL prevents threads from running threads in parallel, but they are efficient given the fact that a thread waiting for I/O tasks can be suspended and allow other thread to run.

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.

@TechWithTim: Awesome tutorial. I used asyncio already in a couple of projects and never really understood the concept of coroutines. What I also came across is Rate Limiting. So it would be awesome if u could add Semaphores in a future video to have a usecase for async API Requests and Concurrency Limiting with Semaphores.

How well does asyncio play with Qt's (PySide) event system? Do they interfere with each other? I'm writing a chat client that uses PySide6 for its UI in order to learn python better and am having a hard time deciding how to handle network I/O with asynchronous socket reads and Qt's signal/slot event system. I know that Qt has it's own networking classes like QTCPSocket but I'm specifically trying to avoid using them in order to learn Python's own native async mechanism. Any advise would be appreciated.

Quick question: Lets assume I make a class with nothing but async functions, if I call the async functions inside another file, lets say I call hello_world() and then I call async_function() and then hello_world() again, would the program freeze while waiting for the hello_world function to execute? Will it execute the hello_world function the 2nd time as the async_function is running?
@TechWithTim8 ай бұрын
well it depends on how you call it, you can't call a coroutine without awaiting it or running it some kind of task or future. So in this case if you awaited it ya it would freeze, but if you ran your hello_world() functions and your async_function() concurrently with tasks then it would not wait, it would go and execute the other hello _world function as soon as it encounters any blocking code

Yes but Async IO gives you direct control of the event loop to control concurrency. In multi threading , the GIL (global Interpreter Lock) only emulates concurrency with kernel handling much of the scheduling side of the control flows
