Statements & Scopes

A statement tells the computer to do something, and a scope contains one or more statements! You can think of a statement as a sentence, and a scope as a paragraph.  

A scope in Python begins with a colon (:), and scopes are defined by indentation. All statements in a scope must start at the same indentation level in order to remain in the same scope!

What does a scope look like?

The code below shows an example of what a scope looks like and how a local scope is started and ended for the greet() function. Take a look at the code and make sure to read the comments to understand which lines are in the local scope of the function.

(Don't worry if you don't understand what the code is doing - we will learn about functions very soon!) 

Scopes are important in understanding functions, so move ahead to learn more about their applications!
