A contact book saved to a file
A complete text adventure game with functions and files
Graphics and drawings with the turtle module

How to use this course

Read each lesson in order the first time. For every exercise, write the code yourself — don't just copy the solution. Mistakes show you exactly what you haven't understood yet, and that's valuable.
