Using Python to Check for Odd or Even Numbers

In this Python Tutorial, beginners will effortlessly learn how to check for odd or even numbers using python. Along with the detailed explanation, you will also see the Python program to check a number is even or odd using different methods. Let’s get into this Tutorial of Using Python to Check for Odd or Even Numbers and become proficient in python programming.

The Tutorial on how to check a number is even or odd in python cover the following stuff: 

Python, how to check if a number is odd or even

It’s moderately straightforward to use Python to make calculations and arithmetic. One cool type of arithmetic that Python can do is to calculate the remainder of one number divided by another. To accomplish this, you have to use the modulo operator (otherwise known as the percentage sign: %).

When you put a modulo in between two numbers, it determines the remainder of the first number divided by the second number. If the second number goes into the first evenly, then there is no remainder and the estimated answer is 0. If the second number doesn’t go into the first evenly, then you’ll have some sort of number stated as the answer.

Check out the following equations to see how it works:

6 % 3
10 % 3

In the first example, 3 goes into 6 evenly (exactly 2 times), so the answer to the equation is 0. In the second example, 3 does not go into ten evenly. It goes into 10 three times, with the remainder of 1. Remember, you’re not trying to find the answer to ten divided by three — the modulo is used to find the remainder of that equation. which is 2. So the answers to the above equations are 0 and 2, respectively.

An excellent way to utilize the modulo in context is to use it to test whether for odd or even numbers. If a number can be divisible by 2 without a remainder, then by definition the number is even. If the number is divided by 2 that equation yields a remainder, then the number must be odd. To put this concept into Python terms, see the code snippet below:

if (num % 2 == 0): #number is even -- insert code to execute here
else: #number is odd -- insert code to execute here

The code above basically states that if the remainder of a number divided by 2 is equal to zero, the number is even. If not, the number is odd. This snippet can be used to execute a number of different functions based on whether or not the number in question is even or odd — insert your functions where it says “insert code here” to add some functionality to the snippet.

Python Program to check if a Number is Odd or Even using Modular Operator

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

number = int(input(" Please Enter any Integer Value : "))

if(number % 2 == 0):
    print("{0} is an Even Number".format(number))
else:
    print("{0} is an Odd Number".format(number))

Output: 

Please Enter any Integer Value : 9
9 is an Odd Number

Python Program to Verify if a Number is Odd or Even

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

number = int(input(" Please Enter any Integer Value : "))

print("{0} is an Even Number".format(number)) if(number % 2 == 0) else print("{0} is an Odd Number".format(number))

Output: 

Please Enter any Integer Value : 24
24 is an Even Number

Python Program To Check A Number Is Even Or Odd Using Bitwise Operator

num=int(input("Enter a number for check odd or even: "))
def find_Evenodd(num)://function definition
    
    if(num&1==1):
        print(num, "is an odd number");
    else:
        print(num, "is an even number");
find_Evenodd(num);//function call

Output: 

Input 1:
Enter a number for check odd or even: 678
678 is an even number

Input 2:
Enter a number for check odd or even: 765
765 is an odd number

Using the Division Operator to Check for Odd or Even Numbers

num=int(input("Enter a number for check odd or even: "))
def find_Evenodd(num)://function definition
    number=(num/2)*2
    if(number==num):
        print(num, "is a even number");
    else:
        print(num, "is a odd number");
find_Evenodd(num);//call the function

Result: 

Enter a number for check odd or even: 987
987 is a odd number
