  • This code here grab an input from the user and determines whether or not the users input follows the criteria of the if statement
  • The user is told to choose a number lower or higher than 10, and if they do, they are rewarded with a message that tells them good job
  • If the user enters 10, then they are frowned upon and are told they couldn’t follow simple directions

  • The code defines a text-based Rock-Paper-Scissors game where the player competes against a computer opponent.
  • It uses a class called RockPaperScissors to manage the game, keep track of wins, losses, and ties, and handle player and computer choices.
  • The game allows players to play multiple rounds and keeps a running score, providing an option to continue or exit after each round.
  • The computer’s choice is determined randomly using the random module, and the game logic is implemented to determine the winner of each round.
