Advice for tool or a script to report a step by step Python file execution

Question

Let's consider the small script above.

def d(n):
    if n==0:
        return 0

    else:
        return d(n−1)

print d(3)

Is there tool that can report each step action as a debugger can do ?

Did you look at the `pdb` (Python debugger) module yet? – Martijn Pieters Nov 20 '13 at 19:00 — Martijn Pieters, Nov 20 '13 at 19:00
I'll try it. My purpose would be to automate the report... – Nov 21 '13 at 16:34 — , Nov 21 '13 at 16:34

You can use Winpdb - A Platform Independent Python Debugger to step through the execution of the script while reviewing the value of each variable at each step, and follow the flow of instructions.

Another option is to use the trace module.

$ python -m trace --trace test.py 
 --- modulename: threading, funcname: settrace
threading.py(90):     _trace_hook = func
 --- modulename: t, funcname: <module>
t.py(1): def d(n):
t.py(6): print d(3)
 --- modulename: t, funcname: d
t.py(2):     if n==0:
t.py(5):         return d(n-1)
 --- modulename: t, funcname: d
t.py(2):     if n==0:
t.py(5):         return d(n-1)
 --- modulename: t, funcname: d
t.py(2):     if n==0:
t.py(5):         return d(n-1)
 --- modulename: t, funcname: d
t.py(2):     if n==0:
t.py(3):         return 0
0

Great ! I'll simply use it via a subprocess. – Nov 22 '13 at 18:33 — , Nov 22 '13 at 18:33
