Learn to write cleaner, more modular, and more scaleable code in Python by gaining a master of Object Oriented Programming (OOP). 

You'll start with the basics of object oriented programming and build up to more advanced concepts such as inheritance, information hiding, and polymorphism. Along the way you'll learn how each concept applies to Python in particular, as well as how various Python features make it particularly convenient for OOP.

This course is filled with hands-on coding challenges, playgrounds, snippets, and illustrations to keep things interactive.

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.
