Question

如何继续要求用户输入有效输入，直到用户输入y值的整数和非零数字为止？我仍在练习While Loop，如果您能帮助我，那就太好了。

提前谢谢！

x = 5
y = 0

while y == 0 or y (is not integer??):
    try:
         z = x/y

    except ZeroDivisionError:
        y = int(input('You cannot divide with "0".\nTry using a number bigger than 0 for y-value.'))

    else:
        print(f'dThanks for placing the right value for y. \nYour result is {z}')
        break

    finally:
        print('All Done')

您可以执行以下操作：

wrong = True
while wrong:
    try:
        number = input("please enter a non-zero number: ")
        if isinstance(int(number), int) and int(number) != 0:
            print('You entered: ' + number)
            y = int(number)
            wrong = False
        else:
            print("make sure it's a nonzero number only!")
    except:
        print("try again please.")

z = x/y

print('The answer is: ' + str(z))

在用户使用While循环在Python上输入整数和非0值之前，如何继续提示用户输入？
