1In coding, every action has a result. When the computer reads print(), the action is 'show text' and the result is the message on screen.
2If we changed the message inside print(), the action stays the same (show text) but the result changes (different text).
3This is cause and effect: the CODE is the cause, the OUTPUT is the effect.
4Every line of code you write causes something to happen. Understanding this helps you predict what your code will do!

Auto-run is on: change the code and the result updates by itself.
