[Baypiggies] Fwd: Tools/libraries to determine the call graph(call flow) of an python program (module/package)

[ashish makani]

Thanks a ton Josh.

I meant the flow of X starts with some function in x.py which in turn calls
some fuction in y.py( not using exec, using imports & simple function
calls), etc etc

Did you mean you have used pycallgraph but it took some massaging the
intermediate date before getting the pretty labelled call flow
graph/diagram ?

Thanks & happy tuesday ! :),
