Embedded Files
A module is a file containing Python definitions and statements intended for use in other Python programs. There are many Python modules that come with Python as part of the standard library. We have already used one of these quite extensively, the turtle module. Recall that once we import the module, we can use things that are defined inside.
Here we are using Screen and Turtle, both of which are defined inside the turtle module.
But what if no one had told us about turtle? How would we know that it exists. How would we know what it can do for us? The answer is to ask for help and the best place to get help about the Python programming environment is to consult with the Python Documentation.
The Python Documentation site for Python version 3 (the home page is shown below) is an extremely useful reference for all aspects of Python. The site contains a listing of all the standard modules that are available with Python (see Global Module Index). You will also see that there is a Language Reference and a Tutorial, as well as installation instructions, how-tos, and frequently asked questions. We encourage you to become familiar with this site and to use it often.
If you have not done so already, take a look at the Global Module Index. Here you will see an alphabetical listing of all the modules that are available as part of the standard library. Find the turtle module.
You can see that all the turtle functionality that we have talked about is there. However, there is so much more. Take some time to read through and familiarize yourself with some of the other things that turtles can do.
Note: Python modules and limitations with Trinket
Not all Python modules will work with Trinket. Here are the ones that will. If you want to try additional modules, you'll need to install Python on your computer.
