Python Modulus OperatorLike other programming languages, the Python modulus operator does the same work to find the modulus of the given number. The operator is a mathematical symbol used to perform different operations such as (+, -, * /) addition, subtraction, multiplication, and division on the given two numbers to return the result in the form of an integer as well as the float number. An operator tells the compiler to perform certain actions based on the passed operator symbol to the given number. Modulus OperatorPython Modulus Operator is an inbuilt operator that returns the remaining numbers by dividing the first number from the second. It is also known as the Python modulo. In Python, the modulus symbol is represented as the percentage (%) symbol. Hence, it is called the remainder operator. Syntax The below is the syntax that represent the modulus operator in Python language, it is used to get the remainder when we divide the first number with the second. Here X and Y are two integer numbers, and the modulus (%) is used in between to get the remainder where the first number (X) is divided by the second number (Y). For example, we have two numbers, 24 and 5. And we can get the remainder by using the modulus or modulo operator between the numbers 24 % 5. Here 24 is divided by 5 that returns 4 as the remainder, and 4 as the quotient. When the first number is completely divisible by another number without leaving any remainder, the result will be 0. For example, we have two numbers, 20 and 5. And we can get the remainder by using the modulus or modulo operator between the numbers 20 % 5. Here 20 is divided by 5 that returns 0 as the remainder, and 4 as the quotient. Get the modulus of two integers numbers using while loopLet's write a program to get the remainder of two numbers using the while loop and modulus (%) operator in Python. Get_rem.py Output: Do you want to continue or not (Y / N)? Y

Explanation: - while True: This creates an infinite loop. The code inside the loop will keep running until the loop is explicitly broken.
- a = input('Do you want to continue or not (Y / N)? '): The user is prompted to enter 'Y' or 'N' to decide whether to continue or exit the program.
- if a.upper() != 'Y': break: If the user enters anything other than 'Y' (case-insensitive), the loop is exited, and the program terminates.
- a = int(input('First number is: ')) and b = int(input('Second number is: ')): The user is prompted to enter two integer numbers.
- print("The result after performing modulus operator is: ", a, ' % ', b, ' = ', a % b): It calculates and prints the result of the modulus operation (a % b) for the first pair of numbers entered.
- print("The result after performing modulus operator is:", b, ' % ', a, ' = ', b % a): It calculates and prints the result of the modulus operation (b % a) for the second pair of numbers entered.
- The program will be asking the user weather we want to continue or we want to stop the program by giving the input like (Y/N), here Y is the input to continue the program and the 'N' is used to stop the program.

Exceptions in Python Modulus operatorIn Python, when a number is divided by zero, it throws an exception, and the exception is called the ZeroDivisionError. In other words, it returns an exception when a number is divisible by a divisor that is zero. Therefore, if we want to remove the exception from the Python modulus operator, the divisor should not be zero. Let's write a program to demonstrate the Python Exception in Modulus operator. Except.py Output: The first number is: 24
The second number is: 0
Cannot divide a number by zero! So, change the value of the right operand. As we can see in the above result, it displays, "Cannot divide a number by zero! So, change the value of the right operand". Hence, we can say, when we divide the first number by zero, it returns an exception. Explanation: - x = int(input('The first number is: ')) and y = int(input('The second number is: ')): The client is provoked to enter two whole number numbers, which are then changed over completely to whole numbers and put away in the factors x and y.

- with the exception of ZeroDivisionError as blunder:: On the off chance that a ZeroDivisionError happens (i.e., assuming the client enters zero as the subsequent number), the code inside the aside from block is executed.
- print('Cannot partition a number by nothing! ' + 'Thus, change the worth of the right operand.'): This line prints a blunder message demonstrating that division by zero isn't permitted and proposes changing the worth of the right operand.
