What's your favorite HTTP library in Python?

[TimL_]

This was brilliant, the more involved topic, the comparisons, discussing correct practices, everything! Keep it up!

[CppExpedition]

Thx Python Engineer for making High Quality Videos!

I love Python! ... the simplicity of Pythonic ethos reverberates through even 3rd party Python modules

It's funny I recently ran into domaintools switching from requests to httpx and didn't know why. Thanks for the run down!

[anthonyaouad]

Small nitpick, can you please use time.perf_counter() instead of time.time() since a lot of beginners watch your videos and it's the better function

[uvle-tsbi]

Thankx for breaking it down.. great tutorial for beginners

[Strikeviolet]

I used this in our project… best library for async and sync requests

[ermalgashimramori]

Great content, looking forward for more.

[daynetran]

This is a great video that came at the right time! I was working with an API for the past week and the part of the pipeline that took the longest was the APi request through the requests library.

Now I'm going to implement this HTTTPX client and also try to work in the Async feature! Thank you! You're awesome!

[toosafelol]

httpx is very good library. amazing asyncio support. at my job we have replaced all httprequests in our code base with this. we used aiohttp and requests in the past.

[Zekei]

I was trying to use this, but you can't pass context to event handlers. This means, for instance, that a response handler only knows the response, but it has no knowledge of what the request was. Handlers are only assigned at the client level (no per-request handlers). So to get different handling for each request, you need a new client. This breaks connection pooling. Ultimately, I went with aiohttp, as it allows passing context per request. Hopefully they add this feature to httpx.

[michak.]

Are there benefits compared to aiohttp? Performance should be comparable, but I'm curious if there is more... probably on testing flask / fastAPI as already mentioned?

[JugaadTech]

Great video. In my experience with large project, its diffcult to use async in general because you dont have async support for lot of important libraries so you either have to mix blocking code with async or you need to re-implement a lot of stuff on your own in async..

Can you compare async against threadpool

[Caedin]

It would have been great if you verified that all the 150 Pokemon were successfully gathered after each time trial. We are just trusting that the outcome of the 0.57 second async gather is equivalent to the 7 second synchronous gathering of Pokemon details. I believe you, but I am skeptical and an extra 2 or 3 seconds in the video to print the contents of the lists after would have been appreciated! Thanks

[vsniney]

Any thoughts on whether additional code would be needed to handle a server's responses such as HTTP rate-limits?

[motaseamyousef]

Hi, thanks for all useful info
Could you please make video list for your shorts videos

[kosmonautofficial]

Great video thanks! Now is this also able to handle well in a multiprocess async fashion? I am looking into aiomultuprocess and not sure if it would be better to run this over aiohttp.

[tusharsnn]

have you tried http2 for making request ? what was the performance difference between http 1.1 vs 2 ? I think requests does not support h2 but httpx does.
