Create RPS.py

A fun little game of rock paper scissors. Takes in user input and checks it to make sure they put in rock, paper, or scissors. If they put in something else, like car, it gives them an error and tells them to put in a correct option. It also allows them to replay the turn without loosing it. Then it randomly generates a choice for the computer. It takes both of they choices and checks to see if it is a tie. If it is a tie, then it will tell them so and tell them to redo the turn. Otherwise it will tell the player who won the turn. There are 3 turns as of now. Each turn the player has time to look at the results and is prompted to 'Press Enter' to play the next round.
