Program 10: Modulo of Two Numbers - 1000+ Python Programs

Question 10) 

10.1) Write a program in Python to find the modulo of two numbers. 
10.2) Python program to find the 10%2 (modulus)
10.3) Write a program to find the modulus of two numbers by taking user input using Python Programming.

What is modulo operation?

The modulo operation in mathematics also known as "modulus" or "mod," is used to find the remainder that results when one number is divided by another.

% is the sign used to represent the modulo operator in mathematics as well as in Python Programming.

Modulo operator takes two operands:

• The Dividend - The number being divided.
• The Divisor - The number that the dividend is being divided by

The result of the modulo operation is the remainder left over after dividing the dividend by the divisor.

Examples of modulo operation

Example 1: Let us perform the operation 13 % 3

The result is 1 because 13 divided by 3 will be 4 with a reminder of 1 as shown in the below working.





Example 2: Let us perform the operation 12 % 4

The result is 0 because 12 divided by 4 will be 3 with a reminder of 0 as 4 is completely divisible by 4, see the below working.

Program 1: Write a program in Python to find the modulo of two numbers

'''
Example 1:
Modulo Python Program
Author: Code2are.org
Date: 21-02-2023
'''

# Let's select a divisor as int number 3
divisor = 3

# Let's select a dividend as int number 13
dividend = 13

#Calculate mod
mod = dividend % divisor

print(f"{dividend} % {divisor} = {mod}")

Output:

13 % 3 = 1

'''
Example 2:
Modulo Python Program
Author: Code2are.org
Date: 21-02-2023
'''

divisor = 2
dividend = 10

mod = dividend % divisor

print(f"{dividend} % {divisor} = {mod}")

Output:

10 % 2 = 0

Write a program to find the modulus of two numbers by taking user input using Python Programming.

'''
Example 3: User input
Modulo Python Program
Author: Code2are.org
Date: 21-02-2023
'''

# Input the first number i.e divisor
divisor = int(input("Enter the divisor number: "))

# Input the second number i.e divisor
dividend = int(input("Enter the dividend number: "))

# Calculate the modulo using the % operator
mod = dividend % divisor

# Print the result to the console
print("The modulo of", dividend, "%", divisor, "is", mod)

Output:

Enter the divisor number: 4
Enter the dividend number: 17
The modulo of 17 % 4 is 1

We have made use of the following Python functions:

1. print(): Built-in function to print a string on the console with f-strings formatting.
2. input(): Built-in function to accept user input
