Question

I want to design a python program that handles exceptions in other programs , I also want this to access the stack trace in python . I am new t python development but am willing to learn but I do not have a direction on where to proceed . Could somebody please point me to a direction / resources that I could follow and maybe develop these skills , specifically what I should be learning to achieve my goal.

I want to develop this on python 2.7

Thank you for your responses.

EDIT : by handling exceptions , I just want to know what exception occured . Like in Java with try catch blocks where you can print out the stack trace and see if it is an arithmetic / array out of bounds error

Hi I was also thinking of something on this line
something like

  try

 (Execute python program here)  // ie import this program 

 except : 1st exception
 except : 2nd exception
 .
 .
 etc

I know how to read from a file , but an unsure if this is correct for just executing a program written by somebody else?

Answer 1

Take a look at the traceback module. It formats and prints stack traces. You can use this is a top-level exception handler.

import sys
import traceback

try:
    do_something()
except:
    ex, val, tb = sys.exc_info()
    traceback.print_exception(ex, val, tb)

Python itself essentially does this on any uncaught excepton, then exits.
