The "sys" module has a reference to the last traceback, strangely enough
called "last_traceback" ;)
You might also want to look at the "traceback" module, as it does some work
for you.

Example:

>>> this_is_just_to_create_an_error
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in ?
    this_is_just_to_create_an_error
NameError: name 'this_is_just_to_create_an_error' is not defined
>>> import sys,traceback
>>> tb=sys.last_traceback
>>> tb_info=traceback.format_tb(tb)
>>> print tb_info
['  File "C:\\PYTHON22\\Tools\\idle\\PyShell.py", line 274, in runcode\n
exec code in self.locals\n', '  File "<pyshell#1>", line 1, in ?\n
this_is_just_to_create_an_error\n']
>>> print ''.join(tb_info)
  File "C:\PYTHON22\Tools\idle\PyShell.py", line 274, in runcode
    exec code in self.locals
  File "<pyshell#1>", line 1, in ?
    this_is_just_to_create_an_error
