There are tools for doing that - Look! - is one I know that works
for C++ and Java but I don;t know iof any freware ones or that
work for Python.

You can run it in any debugger and use the step into/step over
buttons to walk through the code. But it is extremely tiresome!
One of my colleagues once spent nearly two weeks stepping
though some undocumented code we had been given to find
out how it works. He was not a happy man.
If you do go that way I strongly recommend using a graphical
front end like IDLE/Pythonwin/Eclipse(PyDev) etc.

Never come across cProfile but profiling tools generally just
give you a report at the ed of what has been executed.
