Python Async | Asynchronous IO Introduction

[@elg_]

Thank you Zander for this amazing explanation. One thing that make you stand out among 100s of youtubers is that , you will make us understand what is going on behind the scenes ,and not just giving the usage and syntax.

[@TK-zn5fb]

OMG. I tried to learn the same topic couple of weeks ago and it was like learning a new language. This is such a nice explanation. Thanks Zander

[@veryacademy]

Glad it was helpful!

[@IntricateMoon]

BEST TUTORIAL IN ASYNCIO!!! the others were trying hard sound complicated. understood it right away in the first 4 mins

[@veryacademy]

Glad it helped!

[@eltonrr1]

This is easily the best intro to asyncio python tutorial in KZbin. It gives you essentials for you to develop on that basis. I think after this short introduction you can get to at least high level elements described on official documentation with not much of difficulties. For beginners: on the challenge two he asked for a countdown from 10 to 1 and not from 0 to 9 as he performed. The way to do this you have to specify a step in range function: it would be for i in range(10, 0, -1): (...).

[@veryacademy]

Thank you! Sorry about that little mistake!

[@alrehmo]

So far, it is better than any other Python Asyncio tutorials available on KZbin.

[@itsprabinkumarbaniya]

I was waiting for this. Thanks for covering this topics

[@veryacademy]

My pleasure

[@junaidmughal3806]

I understood everything, just need to revise everything a couple of times to make sure that everything is drilled in, thanks for the help

[@okooko9080]

you are a very good teacher .... i struggled to understand asyncio ... but you just have simplified the concept to my understanding with the examples.

[@pietraderdetective8953]

Thank you for the great asyncio tutorial. Also I'm lovin your font size is easy on the eyes. Most KZbin's programming channels got too small font size..it hurts the eyes! Liked and Subscribed!

[@kenrosenberg8835]

No way! I was trying to learn this today!

[@veryacademy]

👍

[@dumi7177]

very good teacher and videos

[@temanangka3820]

Around 23:00 You forrgot not using asyncio.gather(task1, task2) to run task1 and task 2 concurrently. Because this is the essence of async programming you mentioned in first minutes. Without this .gather method, your async program will work just like normal program.

[@蒙先生-v6k]

Thank you Zander for your clear introduction of Python Async. Your presentation let me well understand the concept of Python Async. Thanks

[@makarplakhotniuk3444]

The example with emails made it very practical and thus inderstandable! Thank you very much, sir!

[@ytg6663]

But why not threading. How is it different from that

[@chadgrewal4829]

Best tutorial on this subject. Keep it up :)

[@makiyarichard]

Zander absolute beauty is what can say to your video and content. Just brilliant

[@ermalgashimramori]

Thank you for great explanations.

[@oruchkin]

very good explanation! thank you !

[@veryacademy]

You are welcome!

[@auroshisray9140]

Thanks a lot for clarifying this! Awesome

[@prateeksarangi9187]

Thanks xander !! Great video !! Looking out for more videos on asyncio with coding challenge

[@nedyalkokarabadzhakov5405]

First I like than watch. Thanks

[@prabeshnepal7614]

why didn't the second reply came back at 5.11 , looking at the console both first and third email reply was there, which awaited for 2 seconds. The second email had awaited for 5 seconds but the output was not printed. Please clarify this.

[@vargaswildcat]

Muchas gracias, aunque entre el idioma y el asyncio me he hecho un lío pero mas o menos voy comprendiendo, gracias de nuevo.

[@AcademyOmen]

Oh damn this is awesome. Some async😊

[@JorgeEscobarMX]

25:00 issues when not awaiting tasks.

[@reddysprakash5666]

Hi one of the event is missing in email example can you please check and explain

[@SA-oj3bo]

How to use asyncio to handle multpile tcp server sockets? Will asyncio handle multiple tcp server sockets better than threads do?

[@muhanad102]

does await freeze the UI? for example with tkinter?

[@ahmedghallab5342]

شكرا Thanks

[@pravarsharma]

Can we do the await thing in the same function to skip few lines and then read it back

[@NicolaMastrandrea]

Zander is on 🔥

[@frenkalfredathanase1969]

i have got some thing sir, God bless you

[@AtifShafiinheritance]

Does create task method run these routines in separate thread ( And what are the different use case scenarios for asyncio than threads if routines run in separate threads)

[@felix30ua]

The main difference of asyncio is that everything works in one thread and in one process!!))

[@nachoeigu]

Wow, it is an amazing content. Thank you. I would like to know more about asyncio in Python. How did you learn it? Do you recommend some lecture or article?

[@veryacademy]

Hard to say sorry, this is just knowledge I have obtained over the years! A book like this is useful www.amazon.co.uk/Using-Asyncio-Python-Understanding-Asynchronous/dp/1492075337/ref=asc_df_1492075337/?tag=googshopuk-21&linkCode=df0&hvadid=420608576048&hvpos=&hvnetw=g&hvrand=6431248506474865620&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9045712&hvtargid=pla-1075569750712&psc=1&th=1&psc=1&tag=&ref=&adgrpid=103159542384&hvpone=&hvptwo=&hvadid=420608576048&hvpos=&hvnetw=g&hvrand=6431248506474865620&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9045712&hvtargid=pla-1075569750712

[@akmalatkhamov8760]

As far as I know Python does not allow concurrent programming and I have been living in the paradigm that pure asynchronous programming is not possible. Could you, please, explain, whether it is possible programming of concurrent tasks in Python and whether asynchronous tasks are really asynchronous or pseudo asynchronous?

[@veryacademy]

Hi Akmal. Not normally the type of question that you would see on a beginner tutorial 😁 I will answer the question for others to read too. Async is single-threaded, single-process runs on a single processor or runs one at a time - this tends to be still called concurrency - it fits to some definitions of concurrency being multiple tasks being interleaved. Regarding pure - I would say that asynchronous functions are not usually inherently pure considering that async functions can be again inherently side-effectual. Whether asynchronous tasks are really asynchronous or pseudo asynchronous - well that would depend on how it is implemented - this could be moving into the domains of thread pool task queues and such.

[@akmalatkhamov8760]

@@veryacademythanks a lot for the answer. It seems that I need to do some research)) and your response has given a really good insight, I did not know that asynchronous async tasks can be single-threaded

[@MrRahul15937]

Please, in the beginning of a video, please also introduce these new terms - what are they and where they are used... We are too noob to understand it from the beginning..... I followed your django + react tutorial but got stuck once where you have introduced material ui. What was that thing ? Took me 1 more week to recatch the same video..again..

[@veryacademy]

Noted Rahul. Always tricky to know how best to start off - I like spending time building up and putting in these important aspects - some like to to get on.

[@hasibuzzamantonmoy8845]

Did you try Googling? Works amazing.
