// Chapter 00What is Python?
Collapse▼
Python is a general-purpose, interpreted programming language created by Guido van Rossum in 1991. It reads your code top-to-bottom, line by line — no long compile step. That is why you can go from idea to running program in seconds.

Analogy
Think of the Python interpreter like a live translator at the UN. You speak (write code), the translator converts sentence by sentence (interprets each line), and the audience hears it immediately. No waiting for a full speech to be translated before it starts playing.

Interactive Python 3
print("Hello, World!")print("Python is running!")
You just wrote your first line of code! But for a beginner, even a simple line like print("Hello, World!") can look like alien math. Let us spoon-feed exactly what every single character does:
print
This is the command (or function). It tells the Python computer: "Hey, take whatever I give you next, and push it out to the screen so the human can read it." It literally prints to the console.
( )
These are the delivery hands. Every function needs parentheses. Whatever you put inside the parentheses is the packaged data you are handing over to the `print` command.
" "
These are text protectors (Quotations). Computers are literal. If you just wrote print(Hello), Python would panic, thinking `Hello` is a secret math variable you forgot to define. Wrapping text in " " tells Python: "This is just human text. Don't try to run it or calculate it. Just print it exactly as it looks inside the quotes."
