write a program to check whether a number is even or odd

Hi, in this blog let's try to learn how to write a Python program to check whether a number is even or odd. 

 

 

A number is said to be an even number  if it is completely  modulated by 2. A number is said to be an odd number if it is giving a reminder of 1 when we  modulate by 2


let's consider an example

Let's take two numbers and try to modulate it by 2

number = 18
18 % 2  we get Reminder as 0
So 18 is even number


number = 25
25 % 2  we get Reminder as 1
So 25 is an odd number

Below is the program to check if the number is odd or even


number = int(input("Enter a Number : "))

if number % 2 == 0:
   print("The Number is Even Number")
else:
   print("The Number is Odd Number")

Output:
Enter a Number : 3
The Number is Odd Number

Output:
Enter a Number : 32
The Number is Even Number

Output:
Enter a Number : 355
The Number is Even Number

 

You can also write this Python program using the Bitwise or operator as show below

When you try to use bitwise and operator  with 1 so it will  perform an operation on all the bits,  if it is an odd Number the output will be 1 so let's use this  with  python if statement and try to check if the number is odd  or not.


number = int(input("Enter a Number : "))

if (number & 1):
   print("The Number is Odd Number")
else:
   print("The Number is Even Number")


Output:
Enter a Number : 3
The Number is Odd Number

Output:
Enter a Number : 22
The Number is Even Number

Output:
Enter a Number : 25
The Number is Even Number

python program to check even or odd using function

let's use of modulus with function to check if the number is odd or even

def check_even(temp_number):
   if temp_number % 2 == 0:
        return True


number = int(input("Enter a Number : "))

if (check_even(number)):
   print("The Number is Even Number")
else:
   print("The Number is Odd Number")


OUTPUT:
Enter a Number : 22
The Number is Even Number

OUTPUT:
Enter a Number : 55
The Number is Odd Number

 

Confusion:  Try to run the program by yourself and check if number is odd or not
