使用Python写一个猜拳游戏

以下是一个简单的猜拳游戏的Python代码：

import random

print("Welcome to the game of Rock, Paper, Scissors!")

while True:
    player_choice = input("Please choose Rock (r), Paper (p), or Scissors (s): ")
    if player_choice not in ['r', 'p', 's']:
        print("Invalid input! Please try again.")
        continue

    computer_choice = random.choice(['r', 'p', 's'])
    print("Computer chooses", computer_choice)

    if player_choice == computer_choice:
        print("It's a tie!")
    elif (player_choice == 'r' and computer_choice == 's') \
            or (player_choice == 'p' and computer_choice == 'r') \
            or (player_choice == 's' and computer_choice == 'p'):
        print("Congratulations! You win!")
    else:
        print("Sorry, you lose.")

    play_again = input("Do you want to play again? (y/n): ")
    if play_again != 'y':
        break

print("Thanks for playing!")

该程序使用了一个无限循环，以便玩家可以选择继续玩下去或退出。在每次循环中，玩家输入他们的选择，计算机随机选择一个选项，并比较两个选择以决定获胜者。程序会不断循环，直到玩家选择退出。
