Dear Michael Overall I see a few problems.
0. Functions should return values. Not print them 1. Why use enumerate? The code is not using the index anyway 2. The following line appears wrong. new_output = ' '.join(user_input) 3. This line has a very buggy possibility. new_output.replace(char, new_char) Let us say you have 234. First time you will replace 2 with 3, getting 334. And then you will replace the first 3 with 4 getting 434 and finally end up with 534. Of course due to other coding errors this does not come to pass. But your basic idea of using str.replace() is prone to this problem. 4. How are you supposed to treat 9? Anyway back to your problem: > I want to find all digits in a string and then increment those digits by 1 > and then return the same string with the incremented digits. Pseudocode ------------------ Initialise and outstring (empty) Read the instring character by character if the current character is not a digit append it to outstring else append the transform(current char) to outstring If you can organize your code like this it may be easier HTH Regards Asokan Pichai _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
