# shapes.append(Octagon(Point(350, 320), Point(400, 570))) # remove comment to test Octagon

for shape in shapes:
shape.displayName(win)
shape.displayNumSides(win)
shape.drawShape(win)

win.getMouse()
win.close()

in python please

You will be writing 5 classes for this assignment, a superclass called Shape, and 4 subclasses:
Square, Ball, Triangle, Octagon.
Class Shape
Constructor has 4 parameters and 4 attributes to be listed in this order: numSides, shapeName,
nameAnchor, and messageAnchor. All four attributes should be private.
Methods: displayName and displayNumSides both accept a window object as a parameter. Each
should create and draw a Text object from the graphics library to display the appropriate information.
nameAnchor is the point at which the name will be displayed and messageAnchor is where the
message will be displayed.
Class Square, Ball¹, Triangle, and Octagon
Constructors should accept 2 parameters for the nameAnchor, and messageAnchor. It will call the
super class constructor and pass in the correct number of sides and name for the shape, as well as
the name and message anchor passed by parameter
Each class should aslo have a drawShape method that accepts a window object as a parameter. It
will then build the appropriate shape from the graphics library and draw it appropriately.
Shape Test
Square
A Square has 4 sides
Triangle
A Triangle has 3 sides
Circle
A Circle has 0 sides
Octagon
A Octagon has 8 sides
