如何“完成”代码，使其不只是继续运行

Question

我正在尝试用 Python 制作课堂掷骰子游戏。下面是我的代码。我无法弄清楚游戏如何完成，即选择“n”时，我从未结束重复最终打印（即“，”我希望您喜欢骰子。祝你有美好的一天！“）

import random

import time

player = random.randint(1,6)

ai = random.randint(1,6)

cont = str(input('Roll the dice? Y/N'))

while cont == "Y":

    print ("You are rolling...")

    time.sleep(3)

    print ("You rolled " + str(player))

    print("The computer rolls...." )

    time.sleep(3)

    print ("The computer rolled " + str(ai))

    if player > ai:

        print("You win")

    if ai > player:

        print("You lose")

    cont2 = str(input('Would you like to play again? Y/N'))

while cont != "Y" or cont2 != "Y":

    break

print ("I hope you enjoyed playing dice. Have a great day!")

Answer 1

将下一个用户输入cont2分配给的位置，您只需重新分配给cont。如果用户按“N”，这将“中断”while 循环。然后您将不再需要第二个 while 循环。编辑：正如上面 Daniel 所说，你的代码 nog 总是给出相同的计算机掷骰子。Yoy 应该将ai行更改为while 循环内部。import randomimport timeplayer = random.randint(1,6)# remove ai = random.randint(1,6) herecont = str(input('Roll the dice? Y/N'))while cont == "Y":&nbsp; &nbsp; print ("You are rolling...")&nbsp; &nbsp; time.sleep(3)&nbsp; &nbsp; print ("You rolled " + str(player))&nbsp; &nbsp; print("The computer rolls...." )&nbsp; &nbsp; ai = random.randint(1,6) # <-- add here again&nbsp; &nbsp; time.sleep(3)&nbsp; &nbsp; print ("The computer rolled " + str(ai))&nbsp; &nbsp; if player > ai:&nbsp; &nbsp; &nbsp; &nbsp; print("You win")&nbsp; &nbsp; if ai > player:&nbsp; &nbsp; &nbsp; &nbsp; print("You lose")&nbsp; &nbsp; cont = str(input('Would you like to play again? Y/N')) # <-- this line is changedprint ("I hope you enjoyed playing dice. Have a great day!")您还可以通过.upper()在输入后添加来使其对给定的用户输入更加健壮。所以：cont = str(input('Roll the dice? Y/N')).upper()。如果用户然后输入 'y' 而不是 'Y'，它仍然可以工作。

Have a great day!"只是为了使您的代码更健壮，我在while循环中包含了掷骰子的值。其次，您可以while使用 an摆脱第二个循环，if--else使您的代码更具可读性和可理解性。
