Questions tagged [python-decouple]

Python decouple is frequently used within Python Web Frameworks (e.g. Django or Flask) to store instance settings, so they can be changed without the need of redeploying the whole project or app.

Decouple claims to work better than enviromental variables. Here's an example:

Let's say you have an envvar DEBUG=False. If you run:

if os.environ['DEBUG']:
    print True
else:
    print False

It will print True, because os.environ['DEBUG'] returns the string "False". Since it's a non-empty string, it will be evaluated as True.

Decouple addresses this caveats by allowing casting of values:

config('DEBUG', cast=bool)
