you've got one problem with your situation. if the first part of the 
filename includes letters and numbers, and the second numeric part is 2 
_OR_ 3 numbers, how do you know where the name part ends and the number 
part starts??

is "1foo23012.txt" become "lfoo230, 12" or is it "lfoo23, 012" ??


you should start with the os.path functions to help you manage 
filenames. you can use string functions to determine if characters are 
letters or digits.
