Module 6

Creating your first function

Defining a function with def.

Giving code a name

You define a function with the def keyword, followed by the name, parentheses, and a colon. The body is indented.

Python

def greet():
    print("Hello, scientist!")

greet()
greet()

→ Hello, scientist! Hello, scientist!

The function does nothing until you call it. You can call it as many times as you want.
