This is a good question (because it is one I often ask myself), but it 
is difficult to understand exactly what you seek.

- did you write this library
- is it part of the Python Standard Library, from Pypi, from ...
- are you intending to use the library from your own code
- do you want to "package" this library
???



The short answer is, that it should not be necessary to ask! Each Python 
module, function, etc, should have docstrings 'everywhere' anticipating 
exactly this sort of question!

If it is code you have 'acquired' from elsewhere, then that's already a 
suggestion that it might not be suitable for your use!


In the ?good, old days - and with other languages, we used to have tools 
for 'cross referencing'. Against every identifier, the utility would 
list each line (NR) of code where it was used.

These days, a decent editor/IDE will do much of that.


You may like to review: https://wiki.python.org/moin/DocumentationTools 
which mentions the likes of PyDoc which will go through a module and 
display all of its docstrings. https://docs.python.org/3/library/pydoc.html

The inspect module provides several useful functions to help get 
information about live objects such as modules, classes, methods, 
functions, tracebacks, frame objects, and code objects. For example, it 
can help you examine the contents of a class, retrieve the source code 
of a method, extract and format the argument list for a function, or get 
all the information you need to display a detailed traceback.

Let us know if there's an answer here. Alternately, please refine the 
question giving more, and specific detail...
