Yes, sort of ...  You have to trigger the display yourself within the 
capturing "except" -- it's not automatic.

The traceback module provides a number of functions that can be used to 
display a traceback of the current (or any other) exception.   In 
addition, it can produce a traceback of the current state of the 
execution stack even without an exception:

Example (type this into the Python interpreter):

import traceback
try:
   assert False
except:
   traceback.print_exc()

and you'll get a traceback (a very short one in this case):
 
Traceback (most recent call last):
  File "<stdin>", line 2, in ?
AssertionError
