I would actualy use the following for this particular case..

text = line[n:n+1] or 'nothing'

But in general I think it is best to use exceptions like that only where 
  you expect the code to _not_ throw the exception the majority of 
times. Otherwise the simple condition is better. Although I expect there 
is not much difference either way..
