Lesson 1 — Hello, Python

Your first program

Every program talks to us by producing output. In Python, print() displays whatever you put inside its parentheses. Text (a string) must be wrapped in quotes — "like this". Numbers do not need quotes.

Why it matters: print() is how you see what your code does, so you will use it constantly to check your work and find bugs.

Watch out: forgetting the quotes around text, or the closing parenthesis, is the most common first error.
