This is the third weekly quiz to be taken on Friday, 17 February 2012 after you have completed assignment 3. In order to do this quiz, you must use a computer that has Python and IDLE installed. You may use Dowling's computer laboratory computers or you may install Python on your own computer. In answering questions on this quiz, assume the use of Python, specifically Python 3. Check you answers against both the Dawson text and by actually running IDLE. Be warned that there are differences between Python 2 and Python 3, and you will be marked down for failing to account for those differences. It should take out approximately half an hour to 2 hours to answer these questions. You may not help one another.
