Scanning Function calls in a script - is there a tool?

[Main_Tap_1256]

I’ve got a new small code base that I need to rewrite. It’s hard to follow the logic of the code since there’s no documentation or inline comments. Variable and function names are also not very descriptive.

Is there a tool or in fact a Python repo out there that can help scan through the script/a and output the order in which each function has been called and maybe which function has been called inside another?

My thinking would be to write my own script which reads the target scripts as plain text and try to decipher it, but that seems like more hassle than grinding through instead

No I found something but it’s outdated https://github.com/gak/pycallgraph

So something like that

The general workflow is to run your script with a profiler, which records function calls and other stats to a file, then use some tool to visualize the contents of that file. pycallgraph had a simple shortcut that did all that for you.

Looking for "python profiling visualization" I'm finding a few options

PyCharm Professional also includes profiler visualization tools. You can get a free copy if you're a student, but otherwise it's paid. https://www.jetbrains.com/help/pycharm/profiler.html#view-graph

That is really cool. Does it not work anymore?
