"""
Problem:
Given a file full of madlibs (where certain parts of the sentences can be replaced to make silly sentences),
be able to create a program that can take user input from the prompts of a random sentence, and create
a whole new sentence with the user input
"""

"""
Open up Wordlibs.txt
Import a random line from the Wordlibs.txt
Go through the line and find the various prompts
You will find the various prompts based on finding the first {
The program should find the word inbetween the first { and the second }.
It should then prompt the user for the word in between those curly braces
The program will then take all of those words and combine them.
It will then give the user the sentence with all of the user's given words
Ask the user if they want to play again
If yes, restart the program
If no, end the program
