I see that you are using os.listdir(), so the files should be present, but
still, I would consider checking that when I encounter this error.

Looks good so far, but what are the values in s, r, file and the result of
file.replace(s, r) for the case that fails? Also, as a side note,
help(os.rename) doesn't document any returnvalue to store in n, but that
doesn't seem to be the problem.
