a Class in Python Creating a Class in Python Summary n this lab, you create a programmer-defined class and then use it in a Python program. The program should create two Rectangle objects and find their area and perimeter. nstructions 1. Open the class file named Rectangle.py 2. In the Rectangle class, create two attributes named length and width. 3. Write a public calculateArea method and a public calculatePerimeter method to calculate and return the area of the rectangle and the perimeter of the rectangle. 4. Open the file named MyRectangleClassProgram.py. 5. Set the length of rectanglel to 10.0 and the width to 5.0. Set the length of rectangle2 to 7.0 and the width to 3.0. 6. Print the value of rectanglel's perimeter and area, and then print the value of rectangle2 's perimeter and area.

Summary
3 # Do NOT modify this program. Write your code in Rectangle.py,
4 # then select this file and click "Run Code".
In this lab, you create a programmer-defined class and then use it in a Python program. The
5
program should create two Rectangle objects and find their area and perimeter.
6 from Rectangle import Rectangle
7
8 rectanglel = Rectangle(10.0, 5.0)
9 rectangle2 = Rectangle(7.0, 3.0)
Instructions
10
1. Open the class file named Rectangle.py
11 print("Perimeter of rectanglel is " + str(rectanglel.calculatePerimeter()))
12 print("Area of rectanglel is " + str(rectanglel.calculateArea()))
13 print("Perimeter of rectangle2 is " + str(rectangle2.calculatePerimeter()))
14 print("Area of rectangle2 is " + str(rectangle2.calculateArea()))
2. In the Rectangle class, create two attributes named length and width .
3. Write a public calculateArea method and a public calculatePerimeter method to
15
calculate and return the area of the rectangle and the perimeter of the rectangle.
4. Open the file named MyRectangleClassProgram.py.
5. Set the length of rectanglel to 10.0 and the width to 5.0. Set the length of
rectangle2 to 7.0 and the width to 3.0.
6. Print the value of rectanglel's perimeter and area, and then print the value of
rectangle2 's perimeter and area.
7. Execute the program and verify that the output is correct.
