While循环不中断(Python)

Question

我以前使用过while循环和类似的循环，但是这个循环根本不会达到中断的条件。这个游戏是关于寻找隐藏在盒子里的东西。我添加了一些代码，这些代码在实际游戏中是不会出现的，这可以帮助我验证哪个盒子被隐藏了。盒子的范围从1到5不等，每次游戏重新开始时都是随机的。我一开始把guess-box设置为false，因为我需要一些东西来填充空格，为了以防万一，我把in_box变成了一个字符串。

from random import randrange
in_box = randrange(1, 5)
str(in_box)
guess_box = False
print("To guess which box enter in the numbers that each box relates to, eg, Box 1 will be the number 1! Ready? Set? Go!")
while guess_box != in_box:
print(f"I was in box {in_box}")
guess_box = input("Which box? ")
if guess_box == in_box:
print("Great job, you found me!")
break
else:
print("I'm still hiding!!")
print("Thank you for playing")

Answer 1

您将in_box设置为字符串而未保存它。你需要做in_box=str(in_box):

from random import randrange
in_box = randrange(1, 5)
in_box = str(in_box)
guess_box = False
print("To guess which box enter in the numbers that each box relates to, eg, Box 1 will be the number 1! Ready? Set? Go!")
while guess_box != in_box:
print(f"I was in box {in_box}")
guess_box = input("Which box? ")
if guess_box == in_box:
print("Great job, you found me!")
break
else:
print("I'm still hiding!!")
print("Thank you for playing")

如果没有这个，就永远不会满足终止循环的条件。

Answer 2

您需要将输入强制转换为整数类型，input()的默认类型是str。

结果是像'1' == 1这样的逻辑，它为假，因此条件永远不会通过。

from random import randrange
in_box = randrange(1, 5)
str(in_box)
guess_box = False
print("To guess which box enter in the numbers that each box relates to, eg, Box 1 will be the number 1! Ready? Set? Go!")
while guess_box != in_box:
print(f"I was in box {in_box}")
guess_box = input("Which box? ")
if int(guess_box) == in_box:
print("Great job, you found me!")
break
else:
print("I'm still hiding!!")
print("Thank you for playing")

可以工作，注意在if条件中int()绕过guess-box。
