What is the use of python-dotenv?

Question

Need an example and please explain me the purpose of python-dotenv.
I am kind of confused with the documentation.

Answer 1

In addition to @Will's answer, the python-dotenv module comes with a find_dotenv() that will try to find the .env file.

# settings.py
import os
from dotenv import load_dotenv, find_dotenv

load_dotenv(find_dotenv())

SECRET_KEY = os.environ.get("SECRET_KEY")
DATABASE_PASSWORD = os.environ.get("DATABASE_PASSWORD")
