How to determine odd and even numbers using python

Problem analysis: Use Python to write a program to determine whether the input number is odd or even, and output the information accordingly. To determine whether a number is odd or even, it is based on whether it is an odd number or an even number. The remainder after division by 2. Therefore, you can use the "%" operator to calculate and judge.

The code is as follows:

while True:
    try:
        num=int(input('输入一个整数：')) #判断输入是否为整数
    except ValueError: #不是纯数字需要重新输入
        print("输入的不是整数！")
        continue
    if num%2==0:
        print('偶数')
    else:
        print('奇数')
    brea

Output result

输入一个整数：81
奇数

Or define a function

def judgeOdd(num):
    if num %2 >0:
        return '%i is an odd number.'%num
    else:
        return '%i is an even number.'%num
for i in range(-3,11):
    print(judgeOdd(i))

Output result

-3 is an odd number.
-2 is an even number.
-1 is an odd number.
0 is an even number.
1 is an odd number.
2 is an even number.
3 is an odd number.
4 is an even number.
5 is an odd number.
