Question

import random

min = 1
max = 6

roll_again = "yes"

while roll_again == "yes" or roll_again == "y":
    print ("Rolling Dice...")
    print ("The number is...")
    print (random.randint(min, max))
    print (random.randint(min, max))

roll_again = raw_input("Want to roll again?");

Answer 1

您需要确保用户输入位于while循环中，否则roll_again将永久设置为"yes"，并且您将陷入无限循环。

import random

min = 1
max = 6

roll_again = "yes"

while roll_again == "yes" or roll_again == "y":
    print ("Rolling Dice...")
    print ("The number is...")
    print (random.randint(min, max))
    print (random.randint(min, max))
    roll_again = raw_input("Want to roll again?");

以下是更加pythonic的方法

import random

min = 1
max = 6

while True:
    print ("Rolling Dice...")
    print ("The number is...")
    print (random.randint(min, max))
    print (random.randint(min, max))
    roll_again = input("Want to roll again?");
    if roll_again != "yes" and roll_again != "y":
        break

Answer 2

因为您将循环设置为始终是＆＃34;是＆＃34;。因此，它一遍又一遍地循环，直到它变为假而不会。

试试这个：

import random
while True:
    min = 1
    max = 6

    roll_again = input("Do you want to roll again? Type: Yes or y")

    if roll_again.lower() == "yes" or roll_again == "y":
        print ("Rolling Dice...")
        print ("The number is...")
        print (random.randint(min, max))

此代码将在滚动后每次向用户提示，以查看是否要再次滚动。

当我运行这段代码时，它会反复翻滚。我该如何解决？
