Python Mod Operator Tutorial

In python programming, Python Mod Operator is used to find the remainder of the division of one number by another. In a python programming language, It is represented as a % b. where a and b are positive integer.

The abbreviation of a % b is a mod b.

The main purpose of Python Mod Operator Tutorial is to learn students easily. After reading this tutorial you should know How mod operator is used in programming language and the application of Python Mod Operator in the real-life field.

In Modular arithmetic, the number wraps around the number, when reaching a given value called modulus.

Python mod operator is widely used in Cryptography, Banking, Music, Book Publishing, and other mathematical areas.

How Mod Operator is Calculated

First of all, you should know how the mod operator works in mathematics. Mod operator provides the athematic operation like + , – , / , * , ** . For example:-

13 mod 5 = 3 (That means, when we divide 13 by 5, the remainder is 3.)

7 mod 7 = 0 (That means, when we divide 7 by 7, the remainder is 0.)

6 mod 5 = 1 (That means, when we divide 6 by 5, the remainder is 1.)

25 mod 5 = 0 ( That means, when we divide 25 by 5, the remainder is 0.)

30 mod 7 = 2 (That means, when we divide 30 by 7, the remainder is 2.)

In Arithmetic Modulus all the operations like Add, Subtract, Division, Multiply.Let Consider numbers a and b operated under modulo D.

1. (a + b) mod D = ((a mod D) + (b mod D)) mod D.
2. (a – b) mod D = ((a mod D) – (b mod D)) mod D.
3. (a * b) mod D = ((a mod D) * (b mod D)) mod D.

Python program for the mod operator by taking input from the user

Code

#take input from user 
a= int(input("Enter the value of a : ")) 
b= int(input("Enter the value of b : ")) 

#take a variable as rem for storing the reminder 
#when dividing a by b.
rem = a % b

#print the result.
print("The mod of ", a, "and", b, "is", rem,)

Program for the mod operator by using the function (Python mod operator function)

Code

#Create function for modulus
def ModInPython (a, b):
  rem = a%b
  #print the reminder by using mod operator a mod b.
  print("The value of ", a, "mod", b, "=", rem)

#main Function
if __name__ == "__main__":

  # Take input by the user
  a = int(input("Enter the value of a : "))
  b =int(input("Enter the value of b : "))
  
  # Calling to the function
  ModInPython(a,b)

Program by Using Python mod Libraries

First you should install the mod library in your python IDE

pip install mod

And then write the program for python mod operator. By importing the library

from mod import Mod

from mod import Mod
a = int(input("Enter first number : "))
b = int(input("Enter second number : "))
Mod(a, b)
