**π‘ Problem Formulation:** We often encounter situations in programming where we need to divide two numbers and find out the quotient as well as the remainder. For instance, given two integers, 10 and 3, we want to determine the quotient (which is 3) and the remainder (which is 1) of their division operation.

## Method 1: Using Division and Modulo Operators

This method involves the use of the division `/`

and modulo `%`

operators to obtain the quotient and remainder respectively. The division operator computes the quotient, while the modulo returns the remainder left over when one operand is divided by a second operand.

Here’s an example:

dividend = 10 divisor = 3 quotient = dividend // divisor remainder = dividend % divisor print("Quotient:", quotient) print("Remainder:", remainder)

Output:

Quotient: 3 Remainder: 1

In the code snippet, we assign values to `dividend`

and `divisor`

. We use the floor division `//`

for calculating the quotient to get an integer value. The modulo operation is straightforward, yielding the remainder of the division.

## Method 2: Using divmod() Function

The built-in `divmod()`

function combines the functionality of division and modulus, returning a tuple containing the quotient and remainder of two numbers. It’s a neat and efficient way to perform both operations together.

Here’s an example:

dividend = 10 divisor = 3 quotient, remainder = divmod(dividend, divisor) print("Quotient:", quotient) print("Remainder:", remainder)

Output:

Quotient: 3 Remainder: 1

The `divmod()`

function is used here with two arguments, `dividend`

and `divisor`

. The function returns a tuple, which is then unpacked into `quotient`

and `remainder`

variables, providing a clean and concise way to perform the operation.

## Method 3: Using Integer Division and Multiplication

Another way to calculate the quotient and remainder is by performing integer division to find the quotient and then multiplying the quotient by the divisor and subtracting from the dividend to find the remainder.

Here’s an example:

dividend = 10 divisor = 3 quotient = dividend // divisor remainder = dividend - (quotient * divisor) print("Quotient:", quotient) print("Remainder:", remainder)

Output:

Quotient: 3 Remainder: 1

In the code, after finding the quotient through integer division, we calculate the remainder by multiplying the `quotient`

and `divisor`

and then subtracting that product from the `dividend`

. It’s a bit more complicated but still quite logical.

## Method 4: Using a Custom Function

Creating a custom function is a flexible approach that allows us to encapsulate our logic and reuse it easily. This method is particularly useful when the calculation needs to be performed multiple times throughout a program.

Here’s an example:

def calculate_quotient_remainder(dividend, divisor): quotient = dividend // divisor remainder = dividend % divisor return quotient, remainder dividend = 10 divisor = 3 print("Quotient and Remainder:", calculate_quotient_remainder(dividend, divisor))

Output:

Quotient and Remainder: (3, 1)

This custom function `calculate_quotient_remainder()`

takes two parameters and returns a tuple containing the quotient and remainder. It’s useful for cleaning up your main code and clarifying intent, particularly if this calculation is performed frequently.

## Bonus One-Liner Method 5: Lambda Function

A lambda function allows for a compact representation of a function in a single line of code. It’s mostly used for small anonymous functions that are not intended to be reused extensively elsewhere.

Here’s an example:

quotient_remainder = lambda dividend, divisor: (dividend // divisor, dividend % divisor) print("Quotient and Remainder:", quotient_remainder(10, 3))

Output:

Quotient and Remainder: (3, 1)

The lambda function is defined in one line, taking `dividend`

and `divisor`

as arguments and returning a tuple with the quotient and remainder. This one-liner is the epitome of concise, functional programming in Python.
