Django NameError: name 'os' is not defined

If you've started a new Django 3.1+ project and are using older tutorials or guides, it's likely to come across the following error on your command line:

NameError: name 'os' is not defined

Starting with Django 3.1, the startproject command generates a file that imports pathlib rather than os on the top line.

The quick fix is to import os at the top of your file:

import os # new
from pathlib import Path

The better fix is learn more about how pathlib works and update your BASE_DIR, DATABASES, STATICFILES_DIRS, and other files to use the newer, modern approach.
