Instructions:

BEFORE this session, for each of the following videos or reading:

• Watch the video (or read the reading), and as you do so,

• do the associated quiz in Moodle.

  • You will see that there is an additional (non-Moodle) quiz to do as you watch the videos on CLASSES. Just follow the instructions below.

Videos and Reading:

1. Range expressions
   • Read this document on Python's RANGE expression. It extends the 1-argument form that you know to the 2 and 3-argument forms.
   • As you read the document, do its associated quiz on Moodle.
2. Box-and-Pointer Diagrams
   • Video [9:22 minutes]
   • As you watch the video, do its associated quiz on Moodle.
   • Optional reading: This handout on Box-and-Pointer diagrams covers the same material as the video, plus a little more.
3. What is a CLASS -- the concept
   • Watch this Video [7:44 minutes]. It reviews the concepts of a object and class.

   • As you watch the above video, answer questions 1 to 9 of this Quiz for the Session 8 videos on CLASSES.

     • You do not have to print the quiz (unless you want to). Just hand-write your answers on paper or type your answers into a file, whichever is easier for you.
     • It is likely that you will not know the answers to all of the questions in the above quiz. That is OK — just do what you can.
4. What is a CLASS -- the notation
   • Watch this Video [6:56 minutes]. This video reviews the notation of a class, as well as the concepts. It is important preparation for the next video.

   • As you watch the above video, answer questions 10 to 15 of the above Quiz for the Session 8 videos on CLASSES.

     • Mysteriously, there is no question 12.
     • If question 14 does not make sense to you, no worries, just skip it.
5. What is a CLASS -- the implementation
   • Watch this Video [11:43 minutes].
     • This is the new stuff (but the previous videos are super-important preparation without which this video will make no sense).
     • It shows all the basics of how to implement a class, using a Point class as an example.

   • As you watch the above video, answer questions 16 to 22 of the above Quiz for the Session 8 videos on CLASSES.

     • Reminder: It is likely that you will not know the answers to all of the questions in the above quiz. That is OK — just do what you can.

6. After doing the above, but before doing the in-class project (in PyCharm):

   • Do this Before-the-Session quiz.
   • You do not have to print the quiz (unless you want to). Just hand-write your answers on paper or type your answers into a file, whichever is easier for you.

7. When you are ready to begin the in-class project (in PyCharm):

   • Follow the instructions for doing the Start-the-Session videos.

   • Do NOT begin the exercises in PyCharm until you have followed the instructions on the above page!
