Python: print stack trace after catching exception

examples/python/stack_trace.py

import traceback

def g():
   f()

def f():
   raise Exception("hi")


try:
   g()
except Exception as e:
   track = traceback.format_exc()
   print(track)

print("---------------------")


g()

The upper stack-trace was printed by the traceback module. The lower one would be if we did not catch it.
