Lecture 4 - Functions

• This lectures discusses the concept of functions as a mapping between an input and an output. I discuss examples of functions as formulas and procedures and talk about their use as abstractions, as reusable code, and as organization tools. I give some ideas about how functions are implemented in the spreadsheet tool MS Excel and the programming language Python.
