Turn source code into actions

Tight close-up of a plain text editor showing a file tab labeled `main.py` and readable source code characters like `print("Hi")`, with a small label “source code = text”; no decorative UI, only the editor area.

A program often starts as source code: plain text saved in files like main.py, App.java, or game.c. You can open it in a text editor because it is made of characters, not magic.
