[PYTHON] How to use dotenv

Introduction

I used dotenv this time, so make a note so that you don't forget it.

What is dotenv

By using dotenv, you can set the DB password and information you don't want to see often in .env and read it via settings.py. Do not upload this .env when deploying. You can upload files to GitHub without showing environment variables.

** Installation method **

$ pip install python-dotenv

** Creating an .env file **

Write environment variables to this file. Target the .env file with .gitignore.

USER="username"
PASSWORD = "password"

** Creating settings.py **

import os
from os.path import join, dirname
from dotenv import load_dotenv

load_dotenv(verbose=True)

dotenv_path = join(dirname(__file__), '.env')
load_dotenv(dotenv_path)

USER = os.environ.get("USER")
PASSWORD = os.environ.get("PASSWORD")

main.py


import settings

USER = settings.USER
PASSWORD = settings.PASSWORD

At the end

Please use it as a reference.
