Tutorial 4

0. Library

   Write a list of lists that represents a library of books. Each book in the list should have a title, author, and number of pages stored as part of each book ["The Giver", "Lois Lowry", 240]. Try making your own library of books. Then see if you can do the following things with your library.

   a. Write some code asking for input to add a new book to the library.

   b. Write some code that prints all the titles in the library.

   c. Write some code that prints all the authors in the library.

1. Poker Flush

   Write a program that decides if a list of card numbers is a flush. A flush is a hand in which all 5 cards share one suit. For example the list [6, 0, 11, 2, 5] is a flush because all the cards are clubs.

   Use the first representation shown in the module notes, i.e. the one in Representing Playing Cards.

   Do not remove your test values from the program so I can see how thoroughly you tested your code. You can show me your tests and explain why you chose them when you show me your code.

2. Dedup

   Write a program that removes duplicate values from a list, i.e. if the list starts out as [4, 2, 5, 2, 4], then after your code fragment runs it should be [4, 2, 5].

   Embed your code in the file t4p2kate.py

   (A real-life application would be to remove duplicates from a list of IP addresses so you have a list of unique visitors to your site. In this case the list might look like [ '10.9.0.31', '199.247.52.3', '10.9.0.31', '43.98.12.4', '72.1.3.55', '199.247.52.3', ...]).
