Programming and Algorithms: Week 3

What are we doing this week?

This week we are going to look at the idea of SELECTION, how to give the users choice in out programs.
First we will look at the IF statements, and then a bit of Boolean logic, and finally the CASE statement.
Moving onto the Python side of things we will look at how to implement SELECTION in Python.

Lab #3 is all about checking if what you have learned in the episodes above all makes sense, and if you can use IF statements and the ELIF statement.
