Then, look at each item in that list; check to see whether it's numeric - isdigit() works for this. If it _is_ numeric, convert it to an int, add one to it, and turn it back into a string. Join the list back into a string, and you're done. Note: you can step through the items in a list by saying (for example) "for word in words:" - but if you do it that way you can't modify any of the items. If you need to modify them - by adding 1, for example - you need to refer to them by index instead, and the quickest way to do that is "for x in range(len(words)): print words[x]". That was a bunch of broad hints - if you need help putting them together, feel free to ask.
