石头剪刀布代码Python

石头剪刀布是一个经典的计算机游戏，使用Python编写非常直观。以下是一个简单的石头剪刀布游戏的代码示例：

import random

def game():
    options = ["rock", "paper", "scissors"]
    player_choice = input("Choose (rock, paper, scissors): ").lower()
    
    if player_choice not in options:
        print("Invalid choice! Please choose rock, paper, or scissors.")
        return
    
    computer_choice = random.choice(options)
    print(f"Computer chose: {computer_choice}")
    
    if player_choice == computer_choice:
        print("It's a tie!")
    elif (player_choice == "rock" and computer_choice == "scissors") or \
         (player_choice == "paper" and computer_choice == "rock") or \
         (player_choice == "scissors" and computer_choice == "paper"):
        print("You win!")
    else:
        print("You lose!")

if __name__ == "__main__":
    game()

在这个代码中，玩家输入他们的选择，然后计算机随机选择一个。程序会根据游戏规则（石头胜剪刀，剪刀胜布，布胜石头）判断输赢并给出结果。
