Question

使用python，我必须为学校创建一个用户在电脑上玩的石头剪刀游戏。计算机的选择也必须是随机的。当我尝试运行此代码时，它表示存在语法错误但不是它的位置。有人可以帮忙吗？

    import random

print("Welcome to rock paper scissors.")

player = False

while player == False:
    print(" ")
    print("Press 1 for Rock")
    print("Press 2 for Paper")
    print("Press 3 for Scissors")

    User = int(input("Rock, Paper or Scissors?"))
    Com = random.randrange(1,3)

    if (User == 1) and (Com == 1):
        player = False
    print("Its a draw!")

    elif (User == 2) and (Com == 1):
        player = True
    print("You win!")

    elif (User == 3) and (Com == 1):
        player = True
    print("You lose!")

    elif (User == 1) and (Com == 2):
        player = True
    print("You lose!")

    elif (User == 2) and (Com == 2):
        player = False
    print("Its a draw!")

    elif (User == 3) and (Com == 2):
        player = True
    print("You win!")

    elif (User == 1) and (Com == 3):
        player = True
    print("You win!")

    elif (User == 2) and (Com == 3):
        player = True
    print("You lose!")

    elif (User == 3) and (Com == 3):
        player = False
    print("Its a draw! You both entered scissors.")

    else:
        print("Make sure to enter a number from 1 - 3")

Answer 1

看这里：

if (User == 1) and (Com == 1):
    player = False
print("Its a draw!")

elif (User == 2) and (Com == 1):
    player = True
print("You win!")

print("Its a draw!")的打印声明不属于if。你不能拥有任何“松散”的东西。在if和elif之间。

此外，您的导入是缩进的，但我认为这是格式错误。

它会修复您的错误，但要注意您的命名约定并未对代码进行过多说明。

Answer 2

就像@jedruniu所说，你的缩进不正确。我还冒昧地清理你的代码，这样就不那么容易混淆了：

import random

print("Welcome to rock paper scissors.")

draw = True

while draw:
    print()
    print("Press 1 for Rock")
    print("Press 2 for Paper")
    print("Press 3 for Scissors")
    User = int(input("Rock, Paper or Scissors?"))
    Com = random.randint(1,3)

    if User == Com:
        print("Its a draw!")

    else:
        draw = False #so it doesn't repeat

        if (User == 2) and (Com == 1):
            print("You win!")

        elif (User == 3) and (Com == 1):
            print("You lose!")

        elif (User == 1) and (Com == 2):
            print("You lose!")

        elif (User == 3) and (Com == 2):
            print("You win!")

        elif (User == 1) and (Com == 3):
            print("You win!")

        elif (User == 2) and (Com == 3):
            print("You lose!")

        else:
            print("Make sure to enter a number from 1 - 3")

我的摇滚，纸，剪刀代码有什么问题？
