Question

Python only please, thanks in advance.

Type up the GeometricObject class (code given on the back of the paper). Name this file GeometricObjectClass and store it in the folder you made (xxlab14) 1. Design a class named Rectangle as a subclass of the GeometricObject class. Name the file RectangleClass and place it in the folder. 2. The Rectangle class contains Two float data fields named length and width A constructor that creates a rectangle with the specified fields with default values 4 and 2, respectively The accessor methods for both data fields A method named getArea() that returns the area of the rectangle .A method named getPerimeter(0 that returns the perimeter of the rectangle e A method namedstr_0 that returns a string description of the rectangle (length and width) Write a test program (named TestRectangle , placing it in your folder) that prompts the user to enter the length and width of the rectangle, a color and 1 or 0 to indicate whether the rectangle is filled. The program should create a Rectangle object with these measurements and set the color and filled properties using the input. The program should display the rectangle's area, perimeter, color and True or False to indicate whether the rectangle is filled or not. 3. 4. Include exception handling in the TestRectangle program to take care of the entry of negative numbers or of strings instead of numbers #This program defines the geometric object class. # (It is in a file named GeometricObjectClass) def getArea(self) return self.radius * self.radius math.pi class GeometricObject: init (self, color "green", filled-True): def getDiameter(self) return 2 radius def self.color color self.filled filled def getPerimeter(self) return 2 * math.pi *self.radius def getColor(self) return self.color def_ str_(self) return "circle with radius " + str(self.radius)n"+super) str_0 def setcolor(self, color) self.color color #This program uses the circle class.
