Django: a pattern for settings-configured API clients

Here’s an example of a common pattern in Django projects:

from acme.api import APIClient
from django.conf import settings

acme_client = APIClient(api_key=settings.ACME_API_KEY)


def order_anvil() -> None:
    acme_client.anvils.order(...)

An API client is instantiated as a module-level variable based on some settings. This approach has some drawbacks …
