Hello World

Your First Python Command

When you write a program, the computer does exactly what you tell it — but it won't show you anything unless you specifically ask it to. That's what

print()

Here's how it works:

print("Hello, World!")

Let's break this down piece by piece:

• ◆

  print

  — the name of the command (called a function)
• ◆

  ( )

  — parentheses tell Python "here's what I want you to print"
• ◆

  "Hello, World!"

  — the text you want to display, wrapped in quotes

The quotes are important! They tell Python "this is text, not a command." You can use single quotes

'Hello'

"Hello"

print("Hello!")   # → Hello!
print('Hello!')   # → Hello!  (same result)
print(42)         # → 42  (numbers don't need quotes)
