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.

Learn Object-Oriented Programming in Python

class Car:
    def __init__(self, model, color):
        self.model = model
        self.color = color

    def printDetails(self):
        print("Model:", self.model)
        print("Color:", self.color)


class SedanEngine:
    def start(self):
        print("Car has started.")

    def stop(self):
        print("Car has stopped.")


class Sedan(Car):
    def __init__(self, model, color):
        super().__init__(model, color)
        self.engine = SedanEngine()

    def setStart(self):
        self.engine.start()

    def setStop(self):
        self.engine.stop()


car1 = Sedan("Toyota", "Grey")
car1.setStart()
car1.printDetails()
car1.setStop()


## Explanation
* **Line 2 -- 4**: Initialized car properties

* **Line 6 -- 8**: `printDetails()` prints the properties of `Car`.

* **Line 12 -- 16**: `start()` and `stop()` functions defined with their respective outputs

* **Line 20 -- 22**: Initializer for `Sedan` defined, which also refers to the *parent class* initializer using `super()`

* Created an object of `SedanEngine` and assigned it to the `Sedan` instance property `engine`. 

* **Line 24 -- 25**: `start()` method of `SedanEngine` object is called to start the car.

* **Line 27 -- 28**: `stop()` method of `SedanEngine` object is called to stop the car.
