How to Check if a Number is Even in Python

1. How to Check if a Number is Even in Python This example demonstrates how to check if a number is even in python 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.

2. 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.

3. The Modulo Operator Method Basic Syntax Simple Function Complete Example number % 2 == 0 def is_even(num): return number = 8if number % 2 == num % 2 == 0 0: print("Even")else: The % operator returns the remainder of division. When dividing by 2, even numbers return 0. print("Odd") This function returns True for even numbers, False for odd numbers. A practical implementation with conditional logic.

4. Advanced Techniques 01 02 03 Bitwise AND Method Lambda Function List Comprehension Use number & 1 == 0 for faster performance. This checks the least significant bit. Create concise one-liners: is_even = Filter even numbers from lists: [x for x in numbers if x % 2 == 0] lambda x: x % 2 == 0

5. Practical Applications Real-World Use Cases • Data validation in forms • Algorithm optimization • Game development logic • Statistical analysis • Array processing tasks Even number checking is fundamental in many programming scenarios, from simple
