Question

我是python的新手，我正在尝试运行此简单的嵌套while循环程序，但是我的代码既未显示任何错误，也未执行该功能

import random

player_decision = input("Do you want to roll the Dice ? Type y or n:  ").lower()

if player_decision == "y":
    game_on = True

else:

    game_on = False
    print("Thanks for your time!!")

while game_on is True:
    print("Welcome")

    roll_dice = input("Press R to roll the dice or Q to quit the game  ").upper()

    while roll_dice == "R":
        def rolling():
            outcome = random.randint(1,7)
            print(outcome)

    rolling()

Answer 1

只需将aryerez的注释中的while roll_dice == "R"更改为if roll_dice == "R"

import random

player_decision = input("Do you want to roll the Dice ? Type y or n:  ").lower()

if player_decision == "y":
    game_on = True

else:

    game_on = False
    print("Thanks for your time!!")

while game_on is True:
    print("Welcome")

    roll_dice = input("Press R to roll the dice or Q to quit the game  ").upper()

    if roll_dice == "R":
        def rolling():
            outcome = random.randint(1,7)
            print(outcome)

    rolling()

Answer 2

您在while game_on is True:和if roll_dice == "R":处有2个无限循环（一旦输入它们）。您需要在每次迭代中更改循环进入条件以退出循环。

import random

def decision_making():
    player_decision = input("Do you want to roll the Dice ? Type y or n:  ").lower()
    if player_decision == "y":
        game_on = True
    else:
        game_on = False
        print("Thanks for your time!!")
    return game_on
game_on = decision_making()

while game_on is True:
    print("Welcome")
    roll_dice = input("Press R to roll the dice or Q to quit the game  ").upper()
    while roll_dice == "R":
        def rolling():
            outcome = random.randint(1, 7)
            print(outcome)
        rolling()
        roll_dice = input("Press R to roll the dice or Q to quit the game  ").upper()
    game_on = decision_making()

Answer 3

您在下一个级别{{1}中定义rolling()，但在高度级别中调用if roll_dice == "R":。

只需移动相同的水平即可。

rolling()

函数未在嵌套while循环内执行函数
