Question

我正在尝试创建一个保持得分的石头剪刀游戏，但是当我运行此程序时，每次都会重置分数。我需要改变什么才能保持得分？

import random

def rockPaperScissors():
    playerScore = 0
    computerScore = 0
    print ""
    p = raw_input("Type 'r' for rock, 'p' for paper or 's' for scissors: ")
    choices = ['r', 'p', 's']
    c = random.choice(choices)
    print ""
    print "Your move:", p
    print "Computer's move:", c
    print ""
    if p == c:
        print "Tie"
    elif p == 'r' and c == 's':
        playerScore += 1
        print "You win"
    elif p == 'p' and c == 'r':
        playerScore += 1
        print "You win"
    elif p == 's' and c == 'p':
        playerScore += 1
        print "You win"
    elif c == 'r' and p == 's':
        computerScore += 1
        print "You lose"
    elif c == 'p' and p == 'r':
        computerScore += 1
        print "You lose"
    elif c == 's' and p == 'p':
        computerScore += 1
        print "You lose"
    else:
        print "Try again"
    print ""
    print "Your score:", str(playerScore)+ ", Computer score:", str(computerScore)

while True:
    rockPaperScissors()

Answer 1

你在循环中调用该函数。该函数的第一件事是为分数创建一个局部变量。当功能结束时，该分数被丢弃。它不会通过多次调用持续存在。您应该返回新分数并将新值分配给计数器：

import random

def rockPaperScissors():
    playerScore = 0
    computerScore = 0
    ...
    return playerScore, computerScore

player = 0
computer = 0

while True:
    p, c = rockPaperScissors()
    player += p
    computer += c
    print "Your score:", str(player)+ ", Computer score:", computer

Answer 2

每次运行该功能时，您都会重置分数。在函数之外定义computerScore和playerScore，即使多次运行该函数，它也会保留这些值。使用global将全局变量“导入”到函数范围。

playerScore = 0
computerScore = 0

def rockPaperScissors ():
    global playerScore
    global computerScore
