I'd also like to note that both the inputfiles variable and the readlines() method are superfluous; to iterate through the file line by line, use either
for line in open(inputfilename): # do something with line or (my personal preference, since I like to think of the file as a thing rather than an action) for line in file(inputfilename): # do something with line (Note also that the 'r' argument to open/file is the default and so can be omitted.)
