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.
I've tried the following code, but I am getting the following error. How do I do this properly? def AlterInput(user_input): print user_input new_output = '' for index, char in enumerate(user_input): if char.isdigit(): new_char = int(char) new_char += 1 new_output = ' '.join(user_input) new_output.replace(char, new_char) print new_output def GetUserInput(): '''Get a string from the user and pass it''' user_input = '''I got 432 when I counted, but Jim got 433 which is a lot for only 6 cats, or were there 12 cats?''' AlterInput(user_input.split()) Traceback (most recent call last): File "C:/Python27/Homework/Homework 4_1.py", line 25, in <module> GetUserInput() File "C:/Python27/Homework/Homework 4_1.py", line 23, in GetUserInput AlterInput(user_input.split()) File "C:/Python27/Homework/Homework 4_1.py", line 15, in AlterInput new_output.replace(char, new_char) TypeError: expected a character buffer object Thanks.
