In this issue, the editor will bring you about how to judge odd and even numbers in Python. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Train of thought analysis

The method of determining whether it is odd or even:

In integers, the number that is not divisible by 2 is odd and the number that is divisible by 2 is even.

0 is a special even number. It is not only the dividing line between positive and negative even numbers, but also the watershed between positive odd numbers and negative odd numbers.

Code implementation

Num = int (input ("enter a number:"))

If (num% 2) = = 0:

Print ("{0} is even" .format (num))

Else:

Print ("{0} is odd" .format (num))

The result of running the code:

Enter a number: 54

54 is an even number.

Program analysis

In the program, first prompt the user to enter a number, and then judge whether it can be divisible by 2 according to the number entered by the user. Num%2, which represents whether there is a remainder after dividing num by 2. If it is equal to 0, it means that there is no remainder, that is, num is divisible by 2, then the output num is even, otherwise it is odd.

This is how to judge odd and even numbers in the Python shared by Xiaobian. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
