Python Program to Check if a Number is Odd or Even

In this example, you will learn to check whether a number entered by the user is even or odd.

A number is even if it is perfectly divisible by 2. When the number is divided by 2, we use the remainder operator % to compute the remainder. If the remainder is not zero, the number is odd.

Source Code

# Python program to check if the input number is odd or even.
# A number is even if division by 2 give a remainder of 0.
# If remainder is 1, it is odd number.

num = int(input("Enter a number: "))
if (num % 2) == 0:
   print("{0} is Even".format(num))
else:
   print("{0} is Odd".format(num))

Output 1

Enter a number: 43
43 is Odd

Output 2

Enter a number: 18
18 is Even

In this program, we ask the user for the input and check if the number is odd or even.
