Week 1: Your First Function

Welcome to Week 1 of Python Functions! In this unit, we'll learn how to write our own mini-programs using functions. Functions are like recipes — they give a name to a set of instructions that we can use again and again. This week, we'll focus on the basics: defining a function and calling it. We'll use examples from our classroom friends, like Paul, Emma, and Leo.

Learning goals

• Understand the purpose of functions in Python.
• Use the def keyword to create a function.
• Call a function using its name followed by parentheses.
• Recognize the importance of indentation and the colon.
