Turning in project 1
	Put your name on it!
Review demo:  Function that determines monitor area

A little more on input:
	This is a function, but also a general term in Computer Science
	input to a program:  Information which is needed before something can be performed
	output:  Results of running some part of the program (or the whole thing)
	Think about devices a minute:
		- Input device:  Mouse
		- Output device: In the old days, printers and displays
	These don't have to happen just at the beginning and end
	Format can require some thinking
	
input within a program:
	Programs are often broken into pieces
		- Code re-use
		- Division of effort
		- Establishment of standards (that you don't have to think about anymore)
			+ GNA config example
		- Perhaps most important:  Debugging in parts
		- Further function examples from GNA
	A common mechanism for compartmentalization is functions
		- functions take input as parameters, or arguments
		- They generally don't call input, but can if this is their purpose
			+ For example, in lab4
		- "input to a function" means parameters/argument
	You can't think of every piece of a program at once
	People build stuff this way
		- Computers, cars, etc

Designing standards:
	Programmers design their own little internal standards a lot
	Standards are useful!
		- Example:  VGA
		- Example:  Networking
		- Example:  USB
	Standards constrain innovation
		- Example:  VGA
		- Example:  Networking
		- Example:  USB
	Too many standards is bad
		- Example:  Display connectors, USB

output:  Same thing
	Not always just at the end of the program
	There doesn't have to be any
	Exists within programs (output from a function)
	functions use return to produce output
		- They can also call print

Function general form:
def function_name(parameters):
	function body (possibly including a return)

Further Demos:
	How long to guess the password with number of words?
	Function that converts numbers to strings with leading 0's or spaces

Lists and functions:  A natural combination
	
If we have time:  Memory use, and using it all up
