Lecture 01 -- rough notes
-------------------------

* A computer does exactly what you tell it. Not what you meant.
* A program is a recipe: a fixed sequence of steps.
* Syntax  = is this sentence legal Python?
* Semantics = does this legal sentence mean what I wanted?

Note the name of this file. It has SPACES in it.
Spaces are legal in file names, and they are also the single most common
reason a command typed at the command prompt does not work.

Lab 01 shows you the fix. (It involves quotation marks.)
