Great video. You always give me new knowledge to improve my Python code and don't just settle in the "if it works, don't touch it" mindset.

Really interesting topic. Do you have a video about how memory in python implemented? (about heaps, stacks, references to objects etc.)

[ventsiR]

Please keep doing these, you explain things really well and thoroughly!

[albertwayadav]

Thank you for the video man. Cleared a lot of my querries in just 15 minutes.

great topic to touch on!
other than the speedup benefits, there are consequences as well if we disable garbage collection: memory leaks, manual management is hard.

I also agree with some comments pointing out using gc.collect() manually in a running function makes it slower.

Thank you very much! A great short video really helped me understand GC in python.

Thanks for the interesting video's. Have a nice 2024!

great topic and review, as always, keep it up pybro :)

at 3:53 a reference to L1 from L3 doesn't seem to matter right?

Great video, thank you for making it. Probably not a use-case for me but nonetheless I found the whole topic fascinating, and really well explained. Please consider covering more of these "under the hood" topics.
For about a year I struggled to learn C++ (I'm only a hobbyist) thinking all the while that Python was a bit "mickey mouse". Then I came back to it when I realised that pretty much everything I would want to do was more than catered for in Python. OK, so the trade-off is speed - but that's fine for me, and easily outweighs the fairly complex tool chains that are required for C++.

Awesome explanation. I've a question. When do you suggest to manually turn off GC and what will be the benefits? Say I'm processing a huge set of data and creating a new structure. The size of set is 80K. Now turning of GC will speed up the process but will increase the memory usage. So when should we consider the manual approach?

very interesting thanks a lot. Now I am curious how it's gonna file in a real system with `celery workers` etc.

which video editor you use in pop os, i am getting problem in installing Davinci resolve. Can you help?

Do context managers help to avoid unnecessary garbage in memory?
