how to re-raise an exception with proper stack information

crash_me.py

#!/usr/bin/env python
import sys
import traceback

def f(x):
    a = x / 0
    return a

def g():
    a = {}
    print a[42]

def h():
    try:
        f(12)
    except Exception:
        saved_info = sys.exc_info()
        print 'Exception of type ', saved_info[0]
        try:
            g()
        except Exception:
            print 'An exception during exception handling'
        raise saved_info[0], saved_info[1], saved_info[2]

def main():
    try:
        h()
    except Exception:
        saved_info = sys.exc_info()
        print 'in main'
        traceback.print_tb(saved_info[2])

if __name__ == '__main__':
    main()

But if I want something like this:

1|  try:
2|      f(12)
3|  except TheExceptionIWantToHandle:
4|      handle_it()
5|  except Exception:
6|      saved_info = sys.exc_info()
7|      raise saved_info[0], saved_info[1], saved_info[2]

This is nicer, right?

5|  except Exception:
6|      raise
