Almost always.

If you do not need to know the index numbers of the items in
the sequence, then just iterate over the sequence. So, to
extend your code ...

for n in range(len(files)):
    print 'processing file number', n+1
    file = files[n]
    file.process()


for file in files:
    file.process()
