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.

# Parent Class
class Shape:
    sname = "Shape"

    def getName(self):
        return self.sname


# child class
class XShape(Shape):
    # initializer
    def __init__(self, name):
        self.xsname = name

    def getName(self):  # overriden method
        return (super().getName() + ", " + self.xsname)


circle = XShape("Circle")
print(circle.getName())


// Base Class
class Shape {

  // Private Data Members
  private String name;
  
  public Shape() { // Default Constructor
  	name = "Shape";
  }

  // Getter Function
  public String getName() {
    return name;
  }
  
}

// Derived Class
class XShape extends Shape { 
  
  private String name;
  
  public XShape(String name) { // Default Constructor
    this.name = name;
  }
  
  // Overridden Method
  public String getName() { 
    // write your code here
    
    return super.getName() + ", " + this.name;
  }
  
}

## Explanation

* **Line 16:**  The `super()` function is used to call the **parent class** method `getName()`. With the help of the `super()` function, the `getName()` method returns the parent class `sname`, and which then gets appended with the derived class `xsname` before returning.
