Hi Jake,
I am a noob, trying to learn python along with good practices. Now the queries: The official python-dotenv documentation talks about using the dotenv alongside settings module (python-settings). The load_dotenv() function is also recommended to be put in settings.py. Unable to wrap my head around the following:
Thanks.
Tnx for article! But there is one important caveat here: if you use Linux for example you can not use env names like
HOME
orNAME
orLOGNAME
. Because your app variables from.env
file (in currently working directory) will be overwritten by the global (from Linux).For example: in case you put in
.env
NAME=Michale
and you are logged in as user Daniel, inside your python scriptos.getenv("NAME")
will return Daniel instead of Michael. And most probably this is not something you want in your app....I guess there is different ways to resolve this, but most obvious one for me is to avoid this names entirely and to use some convention like
APP_NAME
orAPP_HOME_DIR
....This is a great way to store API keys or other secrets so that they’re not hard coded into your application!
Absolutely! Thanks for pointing that out. A .env file is a great way to work on a project with those kinds of security concerns in mind without the overhead of storing that information as a system environment variable on your computer.
Really nice writeup! I was just playing around with Python-DotEnv today.
Thanks! While it is a very lightweight package, there’s more to it than I initially realized. I’ve primarily used it as described in the article but it does have features that allow for a few other use cases.
no pip install needed ?
pip install python-dotenv
Thank you so much!
my python script and .env file are in the same folder but somehow it is unable to read the file unless I specify the path.
If you use an Anaconda environment, you can set environment variables in the Conda environment without needing .env files!
Is there any way to add new environment variable into .env file from python code.
you can write inside using this
Thanks, had a chance to try this today
It helped me a lot, thank you!
