无法在python中动态更改变量分数

问题描述

我的计划目标： 每次准备好骰子游戏，两个骰子掷骰子。如果两个数字相等，则玩家获得+5分。否则，得分为-1。 我的麻烦：我的程序无法更改分数。最初设置为0。但是每次只有-1或+5。它必须保持减少或增加。我也尝试了全局变量。 这是我的代码：

from random import randint
    
    
# this function returns two random numbers in list as dice result.
def roll_dice():
    dice1 = randint(1,7)
    dice2 = randint(1,7)
    rolled_dice = [dice1,dice2]
    return rolled_dice
    
    
# game function is all the game,if player is ready.
def game():
    score = 0
    rolled_dice = roll_dice()
    print(rolled_dice)
    if rolled_dice[0] != rolled_dice[1]:
        score -= 1
    elif rolled_dice[0] == rolled_dice[1]:
        score += 5
    print(f"score is {score}")
#also my code in pycharms,not asking if I want to continue game. but ignore it I it bothers you,I can figure it out.
    #help here also if you can.. :)

    conti = input("continue?")
    if conti == 'y':
        game()
    else:
        quit()
    
    
# this is the whole program.
def main():
    ready = input("ready? (y/n)")
    if ready == 'y':
        game()
    elif ready == 'n':
        quit()
    else:
        print("type only y/n")
    
main()

感谢您的帮助。

解决方法

发生重置是因为每次用户键入 y 继续游戏时，您都会继续调用 game（）函数。您可以将您的 game（）函数更改为循环，这将解决您的问题：

def game():
    score = 0
    while True:
        rolled_dice = roll_dice()
        print(rolled_dice)
        if rolled_dice[0] != rolled_dice[1]:
            score -= 1
        else: # you can change here to else,because being equals is the complement of the first if clause
            score += 5
        print(f"score is {score}")

        conti = input("continue?")
        if conti == 'n':
            break
