【问题描述】：

我目前正在 tkinter 中制作石头剪刀布射击游戏，并正在尝试编写一个确定谁获胜的函数。 1 = 石头，2 = 纸，3 = 剪刀。脚本不打印任何内容，除非 comp == 2 和 choice == 1。

def Winning():
    if (((comp == 2) and (choice == 1)) or ((comp == 3) and (choice == 2)) or
        ((comp == 1) and (choice == 3))):
        messagebox.showinfo("Info", "YOU LOSE!!!")
    if (((choice == 2) and (comp == 1)) or ((choice == 3) and (comp == 2)) 
      or ((choice == 1) and (comp == 3))):
        messagebox.showinfo("Info", "YOU WIN!!!")
    else:
        messagebox.showinfo("Info", "DRAW!!!")

【解决方案1】：

我认为你这样做是错误的。假设我们必须使用数字输入，我会这样做：

ROCK, PAPER, SCISSORS = range(1, 4)

roshambo = {
    ROCK: SCISSORS,
    PAPER: ROCK,
    SCISSORS: PAPER
}

def Winning(comp, choice):
    if comp == choice:
        messagebox.showinfo("Info", "DRAW!!!")
    elif comp == roshambo[choice]:
        messagebox.showinfo("Info", "YOU WIN!!!")
    else:
        messagebox.showinfo("Info", "YOU LOSE!!!")

这使您的逻辑清晰并简化了代码。而且，它更容易扩展问题：

ROCK, PAPER, SCISSORS, LIZARD, SPOCK = range(1, 6)

roshambo = {
    ROCK: [LIZARD, SCISSORS],
    PAPER: [ROCK, SPOCK],
    SCISSORS: [PAPER, LIZARD],
    LIZARD: [SPOCK, PAPER],
    SPOCK: [SCISSORS, ROCK]
}

def Winning(comp, choice):
    if comp == choice:
        messagebox.showinfo("Info", "DRAW!!!")
    elif comp in roshambo[choice]:
        messagebox.showinfo("Info", "YOU WIN!!!")
    else:
        messagebox.showinfo("Info", "YOU LOSE!!!")

字典是你的朋友，没有它们就不要编程！

【解决方案2】：

你在哪里获得comp和choice？

这样的事情会起作用：

from tkinter import messagebox

rock=1
paper=2
scissors=3


def Winning(comp, choice):
    if (((comp == 2) and (choice == 1)) or ((comp == 3) and (choice == 2)) or((comp == 1) and (choice == 3))):
        messagebox.showinfo("Info", "YOU LOSE!!!")
    if (((choice == 2) and (comp == 1)) or ((choice == 3) and (comp == 2)) or((choice == 1) and (comp == 3))):
        messagebox.showinfo("Info", "YOU WIN!!!")
    else:
        messagebox.showinfo("Info", "DRAW!!!")


Winning(rock, paper)

这是你想要的吗？

你的函数def Winning():到def Winning(comp, choice):没有任何参数
