[Python] Use Django ORM outside of Django [duplicate]

I'm new to Django and want to use its ORM in my scripts without running whole Django thing. I'm scratching my head how to configure it. Searches on StackOverflow didn't help as answers don't show the full picture.

Therefore, I created a small project:

app.py
manage.py
orm/
__init__.py
models.py


manage.py has configuration:

from django.conf import settings
settings.configure(
DATABASE_ENGINE = 'mysql',
DATABASE_NAME = 'db',
DATABASE_USER = 'admin',
DATABASE_PASSWORD = '',
DATABASE_HOST = 'localhost',
INSTALLED_APPS = ('orm')
)


models.py:

from django.db import models
class Label(models.Model):
name = models.CharField(max_length=50) # required max_length


and finally my main file app.py:

from django.conf import settings
from django.db import models
from orm.models import *
\# do database maniupaltions


Though after running app.py I receive an error that: django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

What am I doing wrong?
