wrap list.index in a try block, e.g:
>>> a = ['test', 'another test']
>>> a.index('yet another test')
Traceback (most recent call last):
File "<interactive input>", line 1, in ?
ValueError: list.index(x): x not in list
>>> try:
... a.index('yet another test')
... except ValueError:
... print "see, no error!"
...
see, no error!
>>>
