Python代码上的错误输出

好的，我是一名编程初学者（显然是Python），我的代码中有一个问题。我刚刚自己编写了代码，使用了我在教程中学到的所有东西。我正在制作一个石头剪刀游戏。实际上，它正在工作，但当我按下numpad'3'时，它会显示my else语句中的代码。有人能帮我吗

import random

playerScore = 0
cpuScore = 0

def rpsGame():

    userInput = int(input("Choose (1)rock (2)paper (3)scissors: "))

    global playerScore
    global cpuScore
    cpuGuess = random.randint(1, 4)

    if userInput == 1 and cpuGuess == 1:
        print("A draw! rock with a rock!")
        print("Player Score:", playerScore, "CPU Score:", cpuScore)

    elif userInput == 1 and cpuGuess == 2:
        print("CPU scores! paper never beats rock!")
        cpuScore += 1
        print("Player Score:", playerScore, "CPU Score:", cpuScore)

    elif userInput == 1 and cpuGuess == 3:
        print("Player scores! rock beats sharp scissors!")
        playerScore += 1
        print("Player Score:", playerScore, "CPU Score:", cpuScore)

    elif userInput == 2 & cpuGuess == 1:
        print("Player! paper never beats rock!")
        playerScore += 1
        print("Player Score:", playerScore, "CPU Score:", cpuScore)

    elif userInput == 2 & cpuGuess == 2:
        print("A draw! paper with a paper!")
        print("Player Score:", playerScore, "CPU Score:", cpuScore)

    elif userInput == 2 & cpuGuess == 3:
        print("CPU scores! paper is cut with scissors!")
        cpuScore += 1
        print("Player Score:", playerScore, "CPU Score:", cpuScore)

    elif userInput == 3 & cpuGuess == 1:
        print("CPU scores! scissors can't cut rock!")
        cpuScore += 1
        print("Player Score:", playerScore, "CPU Score:", cpuScore)

    elif userInput == 3 & cpuGuess == 2:
        print("Player scores! Scissors beat paper")
        playerScore += 1
        print("Player Score:", playerScore, "CPU Score:", cpuScore)

    elif userInput == 3 & cpuGuess == 3:
        print("A draw! scissors with scissors!")
        print("Player Score:", playerScore, "CPU Score:", cpuScore)    
    else:
        print("Error")


while playerScore != 3 or cpuScore != 3:
    rpsGame()

if playerScore >= 3:
    print("Player wins!")

if cpuScore >= 3:
    print("You lose! The opponent won!")

文章中有一个链接，是“错误”的图片。我知道，我在最后的else语句中写了错误，所以我会知道是否有任何问题。

很抱歉有这么长的“else-if”语句，我会在观看和阅读更多Python教程时对其进行更改。感谢您考虑：D

查看random.randint函数。遗憾的是，这与范围或切片不同。所以它进入else语句的原因是cpuGuess==4

---

另外，看看PEP8，我不知道为什么，但每次我看到这个upy downy hilly案例时，我都会有点畏缩。

您的CPU猜测值在1到4之间。将4替换为3

cpuGuess=random.randint（1,4）

应该是：

cpuGuess=random.randint（1，3）

这应该是可行的（我添加了一些代码，只允许输入为1、2或3的数字）

随机导入
playerScore=0
cpuScore=0
def rpsGame（）：
尽管如此：
尝试：
userInput=int（输入（“选择（1）石头（2）布（3）剪刀：”）
除值错误外：
打印（“那不是一个数字！”）
其他：
如果1=3：
打印（“玩家获胜！”）
如果cpuScore>=3：
打印（“你输了！对手赢了！”）

在从

和
切换到
和
的
elif
的中途。为什么？
randint
包含两个端点，因此大约四分之一的时间，您的代码会让计算机选择4，这与任何
if
/
elif
条件都不匹配。哇..没有看到elif和&符号，谢谢注意。回答你的问题，是因为我的电脑在我写代码时坏了，当我再次打开它时，代码保存了一半，我想用“and”代替“elif”，所以我写了“and”。
