Start your work by implementing the ComplexShape class which is a child class of the GeometricShape class. The name attribute of the GeometricShape parent should be set to 'ComplexShape' during the object initialization. The ComplexShape class should have the following private attributes with the associated getter and setter methods: base: The base shape of the complex shape. This is expected to be any child of GeometricShape (i.e., Rectangle, Ellipse, Square, or Circle). However, you do not have to worry about argument validation. holes: The list of holes in the complex shape. This is expected to be a list of GeometricShape's child objects. Again, you do not have to worry about argument validation. The expected behavior: Furthermore, the ComplexShape class should have the following public methods: add_hole: This method with a single hole argument should add the hole to the end of the list of holes. The hole argument should be a child of GeometricShape. remove_hole: This method with a single hole argument should remove the hole from the list of holes. The hole argument should be a child of GeometricShape. Do not worry about the situation when the hole is not present in the list of holes. You will not be graded on the method's behavior in such a situation. get_area: This method should return the area of the complex shape. The area of the complex shape is the area of the base shape minus the area of all holes. get_edge_length: This method should return the total edge length of the complex shape. The edge length of the complex shape is the edge length of the base shape plus the edge length of all holes. As suggested above, do not worry about argument validation in this task. Utilize the Classes Finally, let's observe how we can utilize the implemented classes in our code. First, create a new shapes_example.py file in your project directory. Second, assign the following variables in the shapes_example.py file: rectangle: A Rectangle object with length set to 10 and width to 20. ellipse: An Ellipse object with semi_major_axis set to 9 and semi_minor_axis to 7. square: A Square object with side set to 4. circle: A Circle object with radius set to 20. complex_shape: A ComplexShape object with base set to circle and holes set to [rectangle, ellipse, square]. complex_shape_area: The area of complex_shape. complex_shape_edge_length: The edge length of complex_shape. In this task, you are going to implement one additional class, ComplexShape, in your geometric_shapes. py file. This class will be used to represent a complex shape, which utilizes several geometric shapes. There is always a base which represents the overall shape of the complex shape. Then, there are zeros or more additional shapes that represent holes in the base. The Figure below shows an example of a complex shape with an ellipse base and three holes..

1. Start your work by implementing the ComplexShape class which is a child class of the
GeometricShape class. The name attribute of the GeometricShape parent should be set to
'ComplexShape' during the object initialization.
The ComplexShape class should have the following private attributes with the associated getter
and setter methods:
base: The base shape of the complex shape. This is expected to be any child of GeometricShape
(i.e., Rectangle, Ellipse, Square, or Circle). However, you do not have to worry about argument
validation.
holes: The list of holes in the complex shape. This is expected to be a list of GeometricShape's
child objects. Again, you do not have to worry about argument validation.
The expected behavior:
Furthermore, the ComplexShape class should have the following public methods:
add_hole: This method with a single hole argument should add the hole to the end of the list of
holes. The hole argument should be a child of GeometricShape.
remove_hole: This method with a single hole argument should remove the hole from the list of
holes. The hole argument should be a child of GeometricShape.
Do not worry about the situation when the hole is not present in the list of holes. You will not be
graded on the method's behavior in such a situation.
get_area: This method should return the area of the complex shape. The area of the complex
shape is the area of the base shape minus the area of all holes.
get_edge_length: This method should return the total edge length of the complex shape. The
edge length of the complex shape is the edge length of the base shape plus the edge length of all
holes.
As suggested above, do not worry about argument validation in this task.
Utilize the Classes
Finally, let's observe how we can utilize the implemented classes in our code.
First, create a new shapes_example.py file in your project directory.
Second, assign the following variables in the shapes_example.py file:
rectangle: A Rectangle object with length set to 10 and width to 20.
ellipse: An Ellipse object with semi_major_axis set to 9 and semi_minor_axis to 7.
square: A Square object with side set to 4.
circle: A Circle object with radius set to 20.
complex_shape: A ComplexShape object with base set to circle and holes set to [rectangle,
ellipse, square].

2. complex_shape_area: The area of complex_shape.
complex_shape_edge_length: The edge length of complex_shape. In this task, you are going to
implement one additional class, ComplexShape, in your geometric_shapes. py file. This class
will be used to represent a complex shape, which utilizes several geometric shapes. There is
always a base which represents the overall shape of the complex shape. Then, there are zeros or
more additional shapes that represent holes in the base. The Figure below shows an example of a
complex shape with an ellipse base and three holes.
