Python 2

Make an empty file called __init__.py in the same directory as the files. That will signify to Python that it’s “ok to import from this directory”.

Then just do…

from user import User
from dir import Dir

The same holds true if the files are in a subdirectory – put an __init__.py in the subdirectory as well, and then use regular import statements, with dot notation. For each level of directory, you need to add to the import path.

bin/
    main.py
    classes/
        user.py
        dir.py

So if the directory was named “classes”, then you’d do this:

from classes.user import User
from classes.dir import Dir

Python 3

Same as previous, but prefix the module name with a . if not using a subdirectory:

from .user import User
from .dir import Dir
