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.
