Importing a module or package in Python is a conceptually simple operation:
Find the .py file corresponding to the import. This involves the Python path and some other machinery, but will result in a specific .py file being found.
For every directory level in the import (
import foo.bar.bazhas two levels), find the corresponding__init__.pyfile, and execute it. Executing it simply means running all the top-level statements in the file.Finally, the .py file itself (
foo/bar/baz.pyin this case) is executed, meaning all the top-level statements are executed. All the globals created as a result of that execution are bundled into a module object, and that module object is the result of the import.If none of those steps imported sub-packages, then those sub-packages aren’t available. If they did import sub-packages, then they are available. Package authors can do as they wish.
