用python解决问题

Question

猜数字游戏，当输入的不是整数时，程序会给出“输入内容必须为整数！”的提示，并让用户重新输入

Answer 1

>>> num = None
>>> while not isinstance(num,int):
    try:
        num = int(input('num must be an integer: '))
        print('You input :', num)
    except:
        num = None

        
num must be an integer: a
num must be an integer: 1.1
num must be an integer: 323
You input : 323
>>>
