Python Asyncio, Requests, Aiohttp | Make faster API Calls

[@saminyead1233]

"An event loop is when we let some stuff that takes a long time do it's thing in the background. And when it's all set, the 'event loop' will 'pick it up'." is the most helpful and intuitive definition of event loop I've heard.

[@vnagaravi]

I have so many questions. So, we have two functions running in the background, correct? And another main function, also known as the event loop, continuously monitors both functions for completion. Is it using threading to create worker threads to complete those tasks? And monitoring with the main thread? I kindly request clarification on these matters.

[@venkatramachandran6345]

Incredible. Thank you so much. In the middle of a development that has 300,000 inevitable API calls. Let me check how it works. Again, Thank you

[@PatrickAlphaC]

Good luck!

[@venkatramachandran6345]

@@PatrickAlphaC Processed 320k API with 100 APIs at a time. Out of 320k, 91 got connection error (404). When I rerun the remaining APIs, it worked. How to avoid this connection failure? It looks like a common issue in asyncio but dont see proper fix.

[@jeffreylim5920]

Two things to remember when to use await. 1. You have to await to register the task to the event loop. 2. You have to await the coroutine to return the 'real response'.

[@jeffreylim5920]

The first job takes significant time, and this is why 11:27 method only diminished 4 seconds. (13s -> 9s) So when we do registering job all at once, it saves time and we could enjoy enormous time gain. (13s->1s)

[@carterreynolds5649]

@@jeffreylim5920 yea that's what he said lol...

Yes we need await before get_task(session)

[@lawrencedoliveiro9104]

6:05 Fun fact: asyncio is written in pure Python. What was that about Python not being able to do event loops “natively”?

[@PatrickAlphaC]

I meant more like javascript has the event loop as a first-class citizen.

[@lawrencedoliveiro9104]

@@PatrickAlphaC You mean as a built-in type? Python doesn’t have that, because it doesn’t need it. Remember that, unlike JavaScript, asyncio provides an API for wrapping alternative event loops, it doesn’t force you to use its default BaseEventLoop. For example, every GUI toolkit already provides its own event loop, and Python allows asyncio to work with that.

Great video. would be even better if you could also show how to control number of parallel requests. Uncontrolled parallel requests will trigger dos attack protections and block your further requests.

No, that would be confusing, considering the topic of the tutorial. A step-by-step (keep it simple) approach is preferable.

Great video, my only question would be is, how would you make it async if each time you made a call the url changed and there were headers involved in making the api request? Headers being content type and authentication

You'd have to do a lot more conditionals in the code 😅

[@김성광-q3m]

I'm trying to understand how throwing tasks in an event loop by create_task in tasks list then gather the results(17:02) differs from just executing all tasks at once by gather method(16:38). It seems that gather method not only throws tasks in an event loop but also it executes and waits to be finished(?) so only difference from the two example is that whether you registered the tasks manually by adding create_task or just get them all done by gather method? Did i get it right?

[@EldorJ10]

In in the version 2 of your code you have remove the print statments for printing out the each 60 symbol and print is an i/o bound job which indeed reduces the execution time but i am sure with print statment included the execution time gonna be better that the version 1 thanks awsome job :}

16:41 I get the feeling it only took that time to finish the gather call, that the response collection was not included because it hit an error.

[@samuelh5]

I think it's confusing to call * "dereference," if a person either knows or is about to learn C.

[@PatrickAlphaC]

You're right, I think "unpacking" is the correct term here.

[@gw032sysint9]

It was started very nicely with a real time analogy but then you just moved too fast..some analogy in continuation should be given for async, await, tasks, gather, Analogy for aiohttp also should have meaning once told under what circumstances not to choose requests library
