Getting the dependencies of a function from a library

[Juergen Brendel]

Hello!

Not sure what's vague about the question, I think it was pretty clear.

Imagine this:

>>> import requests
>>>
>>> magic_function(requests.get)
..... prints big output of all other functions and libraries used by 
..... requests.get, plus all the functions used by those functions, 
..... etc. Maybe in some kind of tree representation...


But realistically, I think in Python that's quite difficult to do
reliably in a static manner, considering how you can dynamically change
all sorts of things at run time.

It might be more realistic to do this at run-time, using a dynamically
created call-graph. If you Google for "python call graph" you'll get
numerous hits. This is one of the top ones, to give you an idea of what
kind of output you can expect:

https://pycallgraph.readthedocs.io/en/master/

This call graph will only show the code that was actually called,
though, not all the code (and attributes for that matter) that COULD
conceivably be used under some other circumstances.

Nevertheless, it's a good start to see what your code relies on when
under use.
