Question

Please show all work and answer all parts using python, thanks!

Instructions You will need to create four files: • Shape2D.py - file containing a class definition containing properties all Shapes could possibly have. • Circle.py - file containing a class definition of a Circle that inherits from the Shape2D class. Square.py - file containing a class definition of a Square that inherits from the Shape2D class. • testFile.py - file containing pytest functions testing the Shape2D, Circle, and Square classes, There will be no starter code for this assignment, but rather the class descriptions and required methods are defined in the specification below. It's recommended that you organize your lab work in its own directory. This way all files for a lab are located in a single folder. Also, this will be easy to import various files into your code using the import / from technique shown in lecture. Shape2D.py class The Shape2D.py file will contain the definition of what a general 2D Shape is. We will define this class' attributes as follows: • color - str that represents the color of the shape. You should write a constructor that allows the user to construct a Shape2D object by passing in values for all the fields. You may assume calls to the constructor will always contain a str representing the 2D Shape's color. • _init__(self, color) In addition to your constructor, your class definition should also support "setter" and "getter" methods that can update and retrieve the state of the Shape2D objects: • setColor(self, color) - updates the color of the 2D Shape .getColor(self) - returns the color of the 2D Shape Each 2D Shape object should be able to call a method getShape Properties(self) that you will implement, which returns a str with minimal 2D Shape information. Since a 2D Shape can be many things, the following output represents what will happen if we call the getShape Properties method after constructing a Shape2D object: Shan2hluti
