Understanding Fruitful and Void Functions: A Case Study

Introduction

Functions in Python can be categorized as fruitful or void based on their return value.

Case Study: Calculating the Square of a Number

Approach

1. Fruitful Function: Calculates and returns the square of a number.
2. Void Function: Prints the square of a number without returning anything.

Implementation

def calculateSquare(num):
    return num ** 2

def printSquare(num):
    print("The square of", num, "is:", num ** 2)

number = 5
result1 = calculateSquare(number)  # Fruitful function
print("Result from calculateSquare function:", result1)

printSquare(number)  # Void function

Result from calculateSquare function: 25
The square of 5 is: 25

Conclusion

• Fruitful functions return a value using return, suitable for computations where the result is needed.
• Void functions perform an action directly, such as printing, without returning anything. They’re useful for tasks with side effects but no direct return value needed.
