Project 3 coming this week

This week:  Lists!
	We've been having some good fun with lists anyway
	Let's study them!

Ok, there's a list of methods.  We'll try each of them in turn
	Review note:  List vs. Tuple
	Review demo:  Print out items in reverse order with negative index
	Note:  Strings act like lists most of the time
	Here:  https://docs.python.org/3.5/tutorial/datastructures.html

List comprehensions again:
	We've been using these a fair bit
		- Example
	Functional programming and map(function, list)
		- List comprehensions are more flexible tham map()
	If you're using Python, embrace it!
		- Make me the list of all cars
		- Now find the fastest one in the list
	
Note:  Data Structures, and classes on these

Making a list of results from a command:  .split() on strings
	See the difference?
	Project 2 application
		- Wasting the computer's time

Ok, let's make a graph of how many of each type of file we have!
	Should we use file or extensions?
