Build a program that plays Rock, Paper, Scissors. The program should first accept an integer input from player 1. Then, it should accept an integer input from player 2. For each input, the value 1 represents "rock", 2 represents "paper", and 3 represents "scissors". All other values are invalid. If either player inputs an invalid value, the program should print Error and stop executing.

The program should then determine the winner of the game. If both players choose the same option, the program should print Tie. Otherwise, the program should print either Player 1 Wins or Player 2 Wins, whichever is appropriate for the situation. For example, if player 1 inputs 2, representing "paper", and player 2 inputs 3, representing "scissors", the correct output is Player 2 Wins because scissors beats paper according to the rules of the game.

In python please!
