Python environment variables

Interacting With Environment Variables in Python for App Configuration and Secrets.

Reading .env file

Use Python dotenv Library. Just install the library, create a .env file with your environment variables, and import the environment variables in your code like this:

pip install python-dotenv 

import os
from dotenv import load_dotenv

load_dotenv()

MY_ENV_VAR = os.environ('MY_ENV_VAR')

From the .env file:

MY_ENV_VAR = "This is my env var content."

Accessing GitHub secrets

Add a new secret, go to your GitHub repository > Settings > Secrets > New Repository Secret.

Once added, you can then map them as environment variables in your GitHub actions workflow.

- name: Render Custom Richlink Shortcode
  env:
    MY_ENV_VAR: ${{ secrets.MY_ENV_VAR }}
  run: python your_script.py

Finally, you can use them in Python as follows:

load_dotenv()
MY_ENV_VAR = os.environ['MY_ENV_VAR']
