Day 42: Python Program To Find Quotient And Remainder Of Two Number

 

numerator = int(input("Enter the numerator: "))

denominator = int(input("Enter the denominator: "))

if denominator == 0:

    print("Division by zero is not allowed.")

else:

    quotient = numerator // denominator

    remainder = numerator % denominator

     print(f"The quotient is: {quotient}")

    print(f"The remainder is: {remainder}")

Code Explanation:

1. User Input

numerator = int(input("Enter the numerator: "))

denominator = int(input("Enter the denominator: "))

input(): This function takes user input as a string.

int(): Converts the input string into an integer so that arithmetic operations can be performed.

numerator: The number to be divided.

denominator: The number by which the numerator is divided.

Example Input:

Enter the numerator: 10  

Enter the denominator: 3  

2. Check for Division by Zero

if denominator == 0:

    print("Division by zero is not allowed.")

Why this check?

Division by zero is undefined in mathematics and causes a runtime error in Python.

The condition if denominator == 0 checks if the user entered 0 for the denominator.

If the condition is True, a message is printed:

Division by zero is not allowed.

The program stops further execution in this case.

3. Perform Division

If the denominator is not zero, the program proceeds to calculate the quotient and remainder:

    quotient = numerator // denominator

    remainder = numerator % denominator

// Operator (Integer Division):

Divides the numerator by the denominator and returns the quotient without any decimal places.

Example: 10 // 3 results in 3.

% Operator (Modulus):

Divides the numerator by the denominator and returns the remainder of the division.

Example: 10 % 3 results in 1.

4. Output the Results

    print(f"The quotient is: {quotient}")

    print(f"The remainder is: {remainder}")

f-strings: Used to format strings with variable values.

{quotient} and {remainder} are placeholders that will be replaced with their respective values.

Example Output:

The quotient is: 3  

The remainder is: 1
