Hi,

Then you could also consider using simply lists:

filenames = p'foo', 'bar', baz']
results = []
for name in filenames:
     results.append(some_function(name))

If filenames were generated according to a particular pattern, you can
mimic that pattern and generate filenames list using
list-comprehension, e.g.:

filenames = ['file{nr}.txt'.format(nr=nr) for nr in range(13)]

Chreers,
