(2) Object Oriented Programming.
The assignments and active learning
exercises should help reinforce your understanding.
- To answer a question, you might need to build on knowledge
that you learned previously.
- You may bring one 8.5 inch by 11 inch sheet of double-sided notes.
- You may use a computer to develop your answers.
You may only use the internet to access the interactive python textbook,
the online python documentation or previous python programs

Object Oriented Problem Example
We can represent a rectangle by knowing three things:
the location of its lower left corner, its width, and its height.
Create a class definition for a Rectangle class using this idea.
The following statement should create a Rectangle object
at location (4,5) with width 6 and height 5:
r = Rectangle(Point(4, 5), 6, 5)
Object Oriented Problem Example
Supply the missing class in oop.py
such that the following output is produced when the program is run:
Montana State beat Idaho State on 3/11/2017: 62 to 56
Washington beat Montana State on 3/18/2018: 91 to 63
