Python输入验证：如何将用户输入限制为特定的整数范围？ [英] Python input validation: how to limit user input to a specific range of integers?

问题描述

这里是初学者，正在寻找输入验证的信息。

Beginner here, looking for info on input validation.

我希望用户输入两个值，一个必须是大于零的整数，下一个是1-10之间的整数。对于这两种简单的情况，我已经看到很多输入验证函数看起来过于复杂，有人可以帮忙吗？

I want the user to input two values, one has to be an integer greater than zero, the next an integer between 1-10. I've seen a lot of input validation functions that seem over complicated for these two simple cases, can anyone help?

对于第一个数字（大于0的整数，我有）：

For the first number (integer greater than 0, I have):

while True:
    try:
        number1 = int(input('Number1: '))
    except ValueError:
        print("Not an integer! Please enter an integer.")
        continue
    else:
        break

这也不会检查它是否为阳性，我想这样做。而且第二个我什么都没有。感谢所有帮助！

This also doesn't check if it's positive, which I would like it to do. And I haven't got anything for the second one yet. Any help appreciated!

推荐答案

您可以添加简单的if语句，如果数字不在范围内，则会引发错误。您期望

You could add in a simple if statement and raise an Error if the number isn't within the range you're expecting

while True:
    try:
        number1 = int(input('Number1: '))
        if number1 < 1 or number1 > 10:
            raise ValueError #this will send it to the print message and back to the input option
        break
    except ValueError:
        print("Invalid integer. The number must be in the range of 1-10.")
