- I'm having trouble coding this. python code: Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string, integer, and another string as input, and outputs a sentence using those items as below. The program repeats until the input string is quit.
