Class Activity 1

Welcome to CS 333 - Testing and DevOps! Your first assignment is outlined below:

Project Goals

The goals of this project are to:

1. review basic object oriented principles
2. allow students to explore using the Python programming language

Program

Use Vehicles to explore applying object oriented principles in Python.

Best Practices

• Use a main method to instantiate each class and call functions.
• Each class definition should be in a separate file.

Requirements

1. .py files for each class and the main driver which include each principles as described below
2. a text document with you and your partner's reflections on polymorphism and Python

Encapsulation

• Implement a simple Car class and a Bicycle class.
  • Include constructors and useful properties (like color or name) for each class.
  • Consider useful methods (like start() or pedal()) for each class.

Inheritance

• Both classes should inherit from a Vehicle class.

Polymorphism

• Outside of C++, polymorphism generally refers to runtime polymorphism
  • we would demonstrate that by creating a Vehicle object and assigning a Car to it, calling a function, then assigning a Bicycle object to it and calling the function again.
• If you did that in Python, would it be Polymorphism?
  • Why or why not?

Composition

• Often classes are composed with other classes, for example, a Car and Bike both have Wheels or a Car has an Engine.
  • Create classes for each entity and use composition to add them to your Car or Bicycle class (you may use the same Wheel class for Cars and Bikes)
