Computer architecture: Processor and memory. Their different roles.
The concept of an imperative language.
Python is a language. Difference between interpreted languages and compiled languages.
Getting into the logic of programming. This week we'll "program as an exercise in logic intuition," rather than learning the basics.
Playing with Python.

Variables
Rules for labeling a variable
CamelCase for regular variables, uppercase for constants
Thinking of a variable as a box, or drawer.
Variables can switch contents
Types of values: int, float, string, char
The concept of an algorithm (Section 1.7 in textbook)
Must be unambiguous, executable, and terminating.
Example: calculating the return on a bank account with a yearly interest rate.
Review of the week: some of the concepts covered: variables, literals, integers, reals, strings, functions, statements, comments
