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.

Videos and Reading:

1. Sequences
   • Video [8:43 minutes]
2. The Last Item in a Sequence
   • Video [3:20 minutes]
3. Range expressions
   • Briefly review this document on Python's RANGE expression that you saw in a previous Preparation. It extends the 1-argument form that you know to the 2 and 3-argument forms.
4. Iterating Through a Sequence
   • Video [11:35 minutes]
5. Worms, Python and Ethics: Read this fascinating and important excerpt from a textbook by Horstmann and Necaise.

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!
