What do you do when your Python program is using too much memory? How do you find the spots in your code with memory allocation, especially in large chunks? It turns out that there is not usually an easy answer to these question, but a number of tools exist that can help you figure out where your code is allocating memory. In this article, I’m going to focus on one of them, memory_profiler.

Hey, very useful. Thanks! Similar to ic() for python, but with the nice ability to be used inline.

Icecream is great for this. Just calling ic(foo) gives you the same thing on stderr.

I get around this by using loguru (a wrapper around python's logger), so I get information like the calling function and line number with my debugging statements. I don't use it these days (and actually built something extremely similar around the same time), but icecream is another alternative that facilitates debugging-by-print

Most of the time I simply use icecream (a much better version of print()), and sometimes, I use pudb (a visual debugger) for tougher/trickier bugs.

We also have ice cream

I found icecream in a post on this subreddit and still use it as an alternative to print for debugging.

In the future using something like icecream might be interesting as well.
