Naming Sets of Procedures and Functions

So far we’ve seen names for values, like variables that hold strings and numbers. We’ve also seen how to name (define) functions or procedures and use additional names to store the inputs to those functions or procedures.

Sometimes, you will want to have have a whole group of functions and/or procedures, and you will want to store them somewhere and name that whole set of functions and procedures. In fact, you can. And in fact, you have already used this ability.

That is what you are doing when you execute a statement like from turtle import *. That is where the procedures like forward and right and functions like Screen are defined. We can mix procedures and functions that we define with procedures and functions that we import.
