It would help if you showed us this code. Otherwise we are
just making wild guesses about how you are modelling this.

Also knowing which Python version you are using would be good.

Have you written these functions already?  Are they part of some
module or library you are using? Or is it the writing of these functions 
you want help with?

Graph or network analysis is a fairly standard math problem.
There are probably algorithms (or even solutions) in other
languages (or even in Python if you are lucky) that you can
convert if you do a search.
