Small side point: Try to avoid calling a generator object's .next() method 
directly. Normally, when you _do_ want to do this, you should be calling 
next(files). In Python 3, the magic method is now __next__(), which emphasizes 
that it's for defining, not calling.

As others have pointed out, though, the for loop is the correct tool for this 
job.
