Python: Check Even or Odd

1. Introduction

Determining whether a number is even or odd is one of the foundational tasks in programming. In this blog post, we will explore a simple Python program that checks if a given number is even or odd.

2. Program Overview

1. Take user input for a number.

2. Use the modulus operator to determine if the number is even or odd.

3. Display the result.

3. Code Program

# Python program to check if a number is even or odd

# Taking user input
num = int(input("Enter a number: "))

# Checking if the number is even or odd
if num % 2 == 0:
    print(f"{num} is even.")
else:
    print(f"{num} is odd.")

Output:

(For an input of 7)
Enter a number: 7
7 is odd.

4. Step By Step Explanation

1. The program starts by prompting the user to input a number, which we store in the variable num.

2. We then use the modulus operator (%). If num modulo 2 is 0, then the number is even. Otherwise, it's odd.

3. Based on this condition, we print out whether the number is even or odd. For instance, when the user enters 7, the output is "7 is odd" as showcased above.
