- Usually "dependency" is defined for module / package import.
What you are looking for is a visualizing call flow.

You can still not guarantee that you will not break functionality :)
My experience and solution:
Many a times, I found the call flow data overwhelming and the diagram too complex.
So what i usually do is trace call flow partially for the function, I am interested in.
This is done by utilizing the sys.settrace(...) function. After generating the call flows as textual data, I generate a call graph using graphviz.

- On call tracing
- For generating graphs, use graphviz solutions from networkX.
[Edit: based on comments]
Then my piecemeal solution works better. Just insert the code and use the decorator on a function that you want to trace. You will see gaps where deferred comes into picture but that can be worked out. You will not get the complete picture directly.
I have been trying to do that and made a few post that works on that understanding.
