I created the .env file using the command and created variables like token_id="13423edq234" and so on. I don't want to use an external package like dotenv to read the file. I just want to know if there's any way to load the .env file that I've created so that it can be read by Python. Also I don't want to add the env variable to zprofile.
vim .env
and in the Python 3 shell,
import os
os.environ['token_id']
and it says, it's not defined.
You can source it before running it:
$ source .env
$ python
>>> import os
>>> os.environ['token_id']
Main criteria for searching for a solution is to not populate the .profile or .bash etc files with custom environment variables. I've found a solution that works quite well for me.
direnv is a package that I came across. It works with Unix based OS. Since I use a mac with zsh shell, it works amazing. Here's the link to install direnv.
After you follow the installation instructions, create a .envrc file and write your custom env variables, in my case, it would be like this in the .envrc file.
export token_id="13423edq234"
The best part is that it loads and unloads the variables automatically so your .profile stays clean. Let me know if you have any doubts.
Like @Vaibhav, I use direnv with the following .envrc file:
[ -f secrets ] && eval $(cat secrets | sed 's/^/export /') || echo "no secrets file"
Then you can have a secrets file (or call it .env if you like and update the .envrc file accordingly):
MY_ENV_VAR1 = foo
MY_ENV_VAR2 = bar
The sed part of the .envrc allows you to optionally include the export statement in the secrets/.env file.
Googling for "dotenv python" returns several relevant documents. Such as this python package: https://pypi.org/project/python-dotenv/. And this Stack Overflow question: Can somebody explain the use of python-dotenv Module.
