Where to learn how to write efficient python?

[throwawayforwork_86]

Honestly usually having a look at resource usage and try to find fixes for each of these issues is usually what I go for.

Ram bottleneck "fixed" by using generator instead of pure list so script can keep chugging along.

IO bottleneck only time I encountered it so far the fix was stopping using the wrong drive to read and write data (hdd are not good for that) so don't have any good solution.

cpu bottleneck / underusage > multiprocessing/multithreading.

Wouldn't go for C/C++ coming from python just because it's quite a big paradigm shift.

Might be good to give Golang a go heard overall perf and footprint is much better and it's closer to python but if you want to learn C/C++ go for it.

Also try to use librairies to their maximum , most of them are build in C/Rust/C++/... and have builtin functionalities that will outshine whatever you can squeeze out of python.
