Work with the pillars of OOP in Python, including classes, inheritance, and polymorphism.

Python for Programmers

In this module, we’ll learn to write cleaner, more modular, and more scalable code in Python by gaining mastery in object-oriented programming (OOP). We'll start with the basics of object-oriented programming and move to more advanced concepts such as inheritance, information hiding, and polymorphism. Along the way, we'll learn how each concept applies to Python in particular, as well as how various Python features make it particularly convenient for OOP. This module has hands-on coding challenges, playgrounds, snippets, and illustrations to keep things interactive.

Object-Oriented Programming in Python

class Point:
    def __init__(self, x, y, z):
        self.x = x
        self.y = y
        self.z = z

    def sqSum(self):
        a = self.x * self.x
        b = self.y * self.y
        c = self.z * self.z
        return(a + b + c)


obj1 = Point(4, 5, 6)
print(obj1.sqSum())


// Square Sum
class SquareSum {

  // Method to square the sum of three numbers
  double squareSum(double num1, double num2, double num3) {
    double sum = 0;

    num1 = num1 * num1;
    num2 = num2 * num2;
    num3 = num3 * num3;
    sum = num1 + num2 + num3;

    return sum;
  }
}

# Explanation

Let’s look at the solution for each task one by one.
## Task 1
* We passed parameters and assigned them to their corresponding properties.
## Task 2
* We calculated the squares of the properties by multiplying them with itself and stored them in a variable. 
* Then, we added all the squared numbers.
* Finally, we returned their sum.
