python - 石头剪刀布不打印结果

Question

我正在尝试针对计算机创建剪刀石头布程序，但遇到了一些问题。

我做了两种方法，一种是计算机的选择，一种是用户的选择。对于计算机来说，它随机生成 0,1,2 并从我声明为局部变量 rps 的数组中选择石头、布或剪刀。当我尝试使用 game_play() 方法运行游戏时，我可以输入输入，但无法在玩家和计算机之间获得结果输出。

class RockPaperScissors():
    global rps
    rps = ['rock', 'paper','scissors']

    def computer_choice(self): #computer randomly picks rock paper or scissors
        x = random.randint(0,2)
        w = rps[x]
        return w
        #print(rps[x])

    def player_choice(self): #does the player choose rock paper or scissors
        x = True 
        while x:
            choice = (input("Player- would you like rock, paper, or scissors? enter rock,paper, or scissors?: "))
            if choice.lower() == 'rock':
                    return 'rock'
            elif choice.lower() == 'paper':
                    return 'paper'
            elif choice.lower() == 'scissors':
                    return 'scissors'
            else:
                ("please enter in rock, paper or scissors")

    def game_play(self):
        rock = RockPaperScissors()
        user = rock.player_choice()
        comp= rock.computer_choice()

        if comp == 'rock' and user == 'paper':
            return "the player wins!"
        elif comp == 'rock' and user == 'scissors':
            return "the computer wins!"
        elif comp == 'paper' and user == 'rock':
            return "the computer wins!"
        elif comp == 'paper' and user == 'scissors':
            return "the player wins!"
        elif comp == 'scissors' and user == 'paper':                        
            return"the computer wins!"
        elif comp == 'scissors' and user == 'rock':
            return "the player wins"

我正在尝试这样测试:

rock = RockPaperScissors()
rock.game_play()

Answer 1

如果您将其作为脚本运行，而不是在 Python 解释器中运行所有内容。您必须显式打印该值。

一种可能的解决方案是:

rock = RockPaperScissors()
print(rock.game_play())
