Hands-On Software Engineering with Python

Packages in a project's context

Within the src directory is the package tree for the project. Each directory level at or under the example_project directory that has an __init__.py file is a formal Python package, and will be accessible through an import statement in Python code. Once this project is built and installed, then, and assuming that the code within it is written to accommodate the relevant import structure, all of the following would be legitimate imports from the project's code:

import example_project	Imports the entire example_project namespace
import example_project.package	Imports example_project.package and all its members
from example_project import package
from example_project.package import member
