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

To understand this example, you should have the knowledge of the following Python programming topics:

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 gives a remainder of 0. # If the remainder is 1, it is an 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. Please note that `{ }`

is a replacement field for `num`
