Python代码

Question

好的，我是编程的初学者（显然是在Python中），我的代码中存在问题。我自己编写了代码，使用了我在教程中学到的所有东西。我正在制作一个摇滚纸剪刀游戏。实际上，它正在工作，但是当我按下numpad'3'时，它会显示我的其他声明中的代码。有人可以帮我这个吗？

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!")

帖子中有一个链接，就是'错误'的图片。我知道，我在最后的其他声明中写了错误，所以我知道是否有任何问题。 对于长的“else if”语句，我会在观看和阅读更多有关Python的教程时更改它。感谢您考虑：D

Answer 1

您的CPU猜测是CPU猜测在1和4之间。将4替换为3。

cpuGuess = random.randint(1, 4)

应该是：

cpuGuess = random.randint(1, 3)

Answer 2

这应该有用（我添加了一些代码，只允许输入为1,2或3的数字）。

import random

playerScore = 0
cpuScore = 0

def rpsGame():
    while True:
        try:
            userInput = int(input("Choose (1)rock (2)paper (3)scissors: "))
        except ValueError:
            print("That\'s not a number!")
        else:
            if 1 <= userInput < 3: 
                break
            else:
                print("Out of range. Try again")

    global playerScore
    global cpuScore
    cpuGuess = random.randint(1, 3)

    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 and cpuGuess == 1:
        print("Player! paper never beats rock!")
        playerScore += 1
        print("Player Score:", playerScore, "CPU Score:", cpuScore)
    elif userInput == 2 and cpuGuess == 2:
        print("A draw! paper with a paper!")
        print("Player Score:", playerScore, "CPU Score:", cpuScore)
    elif userInput == 2 and cpuGuess == 3:
        print("CPU scores! paper is cut with scissors!")
        cpuScore += 1
        print("Player Score:", playerScore, "CPU Score:", cpuScore)
    elif userInput == 3 and cpuGuess == 1:
        print("CPU scores! scissors can't cut rock!")
        cpuScore += 1
        print("Player Score:", playerScore, "CPU Score:", cpuScore)
    elif userInput == 3 and cpuGuess == 2:
        print("Player scores! Scissors beat paper")
        playerScore += 1
        print("Player Score:", playerScore, "CPU Score:", cpuScore)
    elif userInput == 3 and 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!")

Answer 3

查看random.randint函数。可悲的是它与范围或切片不一样。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，但每当我看到这种暴躁的丘陵情况时，我只会畏缩一点。
