Making a Package

In the previous chapter, we saw how to install Python and third-party packages of code that we can use with Python. In this chapter, we'll see how packages are represented on the computer's filesystem. We'll take a look at how to add code modules inside the package, how to make those code modules interact with each other within the package, and how to access data from non-code files that are incorporated into our package.

By the end of this chapter, you'll have a pretty good idea about how to create your own packages of Python code. Packages will form the basis for programs and help you to make your code modular.

In this chapter, we will cover the following topics:

• Creating an empty package
• Adding modules to the package
• Accessing code from other modules
• Adding static data files to the package
