Taking Notes

Let's understand something in detail:  Assignment to variables
	A variable must be created
		- This requires type to be determined
		- Historical language precedent
		- C++11 auto
		- Historical C and Ada
	Assignment direction

Ok, let's talk about lab1start.py

Calculations can be done a line at a time.
	How many elephants would it take to drink a swimming pool?
	Input in this case is by changing variables
	Launching the elephants

Expressions in Python:
	Arithmatic:  + - * / % **
	Comparison:  == <= >= < > 
	Logic:  and or not 
	Assignment doesn't act like an operator in Python
	Order of operations and parenthesis
	Use parenthesis if you need them or think you do
		- But don't make a mess
	Example:  Do the previous examples on one line each

Variables can store multiple types, including logic values
Logic values are useful for conditionals, like "if" statements

"if":
	Example:  Warn if you don't have enough pool for enough elephants
	
"else" and "elif":
	Used to choose a few options
	Exactly one branch is chosen
	Block is deliminated by tab characters or spaces

"while":  Keep on repeating while something is true
	Like an "if" statement, but repeats
	Would "else" make sense with "while"?
