Getting the name which is not defined from NameError in python

Question

As you know, if we simply do:

>>> a > 0
Traceback (most recent call last):
  File \"\", line 1, in 
    a > 0
N         


        

Answer 1

>>> import exceptions
>>> try:
...     a > 0
... except exceptions.NameError, e:
...     print e
... 
name 'a' is not defined
>>> 

You can parse exceptions string for '' to extract value.
