This document provides instructions for an introductory lesson on computer programming using Python 3. It outlines vocabulary terms like Python 3, IDE, output, and syntax error. Learners are instructed to write a list of apps used that day, learn that Python runs on all computers, and write their first "Hello World!" program in IDLE, finding ways to make mistakes. Homework includes installing Python and reading about "Hello World!" programs.

1. Programs, programs, everywhere!
This is a starter activity and should take 5 minutes

2. Write a list of all the apps, programs and applications you
have used so far today.
3. Be ready to share your ideas with the class.
