Lesson 1 · Unit A: Hello, Builder

Goal: Use print() to make Python show text on the screen.

Every program you will ever build starts the same way: you tell the computer to do something, and it does it. In Python, the simplest command is print(). Whatever you put inside the parentheses shows up on the screen.

Text goes inside quotation marks. Python calls text a string. You can even multiply a string to repeat it, which is handy for drawing lines and borders.
