I won't ask for subscriptions / likes / comments in videos but it really helps the channel. If you have any suggestions or things you'd like to see please comment below!

Another fantastic walkthrough, I really enjoy these breakdowns. Makes me wonder if a simple pytest plugin could be made to prevent these "catastrophic" import time regressions, especially for these packages that are widely depended on. Do you have a resource for reading the output of the profiling graph? I've always struggled to understand how they're supposed to be read.

[@anthonywritescode]

yeah! I talk a little bit about self time vs cumulative time in the linked video in the description (that's honestly the most significant thing to look at most of the time)

[@akshaymestry7503]

Always something to learn... I know you have planned out a couple of things that you want to make videos upon, one suggestion... Can you please a dedicated playlist on topics like Git, Bash and Profiling? I know I know you have already created videos on those topics and you link the dependent videos below in the desc too... but what if there are dedicated vids for respective topics and there you teach us all the great stuff you do, stuffs like how you come up with bisecting a branch, how to name the branch correctly (pyparsing didn't have your usual branching nomenclature), your bash skills (my god! those are amazing!!!), stuffs with profiling, etc. What do you think about that? Please let me know. I have asked all my junior colleagues to watch your videos for learning and some of them are already impressed!

[@anthonywritescode]

heh it's already a lot of work to maintain the current playlist -- I've been trying to think of ways to let users classify the current videos into separated lists and then have playlists like that -- but I already forget to properly assign the current set of videos, I'd surely forget when classifying more let me know if you have any thoughts on that as an idea and how someone might be able to contribute to that

[@akshaymestry7503]

@@anthonywritescode Can we (your subscribers) create and sort or arrange your vids into playlists? Let me know if I should do that for you. I'll check on youtube on how to do that.

[@anthonywritescode]

it's possible to make personal playlists but not channel ones -- I would likely need to build something since youtube doesn't have fine-grained permissions to channels (basically it's "owner", "full access" or "official comments" only)

[@Jakub1989YTb]

Maybe add another set of tags in the name of the video and then we may try youtube chanel search. I'm not sure, but maybe it searches description too? Those tags would then be added only in description.

Is there a way to disable pip from writing to cache, for the --no-cache-dir option only disables gettig from cache

[@anthonywritescode]

that also should disable writes too -- it does so for me at least

Hi i need your advice i want to choose typing for returning __code__ of function, but cant find right typing for that, can you indicate where to look

[@anthonywritescode]

should be `types.CodeType` github.com/python/typeshed/blob/693c4f19b495c810862dc196dba04bc548d22a8a/stdlib/builtins.pyi#L847
