Be sure to watch the videos very carefully, and not just
skip ahead to the parts required to answer these questions!

Be *very brief* in your answers!  Seriously.  Brief.

1. Your full name and andrew id:

2. The full names and andrew id's of your groupmates, if you worked in a group.

4. Total time this check required (fill this out when you are done):

5. Strings questions (from the various String videos):

5.5. For any string s where len(s)>1, is it definitely true that ((s[1:] in s) == True)?

5.6. What is the empty string?  What is its type?  What is its length?

5.7. What is "abcde"[-1]?

5.8. What is 'abcde'[-1][-1]?  Briefly explain why that works, but 'abcde'[1][1] crashes.

5.10. Briefly, what is the difference between split and splitlines?

5.11. Please be sure to carefully watch the videos and take time
to discuss and reflect on their content, and not just hurry through
and answer all these questions.  The point of this check is not for
you to answer the questions, but for you to learn the material.  So
please take the time to learn the material well.  Ok?
