# Python Program to Check if a Number is Odd or Even

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`.

• If the given number is odd, return `"Odd"`.
• If the given number is even, return `"Even"`.
• For example, for input 4, the output should be `"Even"`.
