How to Check if a Number is Even in Python This example demonstrates how to check if a number is even in python using the modulo operator ( % 2 ). The function returns “even” for numbers divisible by 2, and “odd” otherwise. It works for positive, negative, and zero values, illustrating a fundamental Python conditional technique. Understanding Even Numbers What Makes a Number Even? An even number is any integer that is divisible by 2 with no remainder. Examples include 2, 4, 6, 8, 10, and so on. In programming, we use the modulo operator (%) to find the remainder of a division operation. If a number divided by 2 has a remainder of 0, it's even. The Modulo Operator Method Basic Syntax number % 2 == 0 The % operator returns the remainder of division. When dividing by 2, even numbers return 0. Simple Function def is_even(num): return num % 2 == 0 This function returns True for even numbers, False for odd numbers. Complete Example number = 8if number % 2 == 0: print("Even")else: print("Odd") A practical implementation with conditional logic. Advanced Techniques 01 Bitwise AND Method Use number & 1 == 0 for faster performance. This checks the least significant bit. 02 Lambda Function Create concise one - liners: is_even = lambda x: x % 2 == 0 03 List Comprehension Filter even numbers from lists: [x for x in numbers if x % 2 == 0] Practical Applications Real - World Use Cases • Data validation in forms • Algorithm optimization • Game development logic • Statistical analysis • Array processing tasks Thank You Contact Information Address: 319 Clematis Street - Suite 900West Palm Beach, FL 33401 Email : support@vultr.com Website : vultr.com
