How to Use Python Decouple

Django has lot of sensitive data in settings.py file, By default its visible to everyone. so we need to protect the sensitive data for that we will use python decouple.

  • Decouple supports both .ini and .env files.
  • First create a file named .env in the root of your project. You can also use a .ini file.
  • Now install python decouple using below command
pip install python-decouple
  • Then use it on your settings.py
from decouple import config

#Retrieve the configuration parameters
SECRET_KEY = config('SECRET_KEY')
DEBUG = config('DEBUG', default=False, cast=bool)
EMAIL_HOST = config('EMAIL_HOST', default='localhost')
EMAIL_PORT = config('EMAIL_PORT', default=25, cast=int)

How Python Decouple will works: Decouple always searches for Options in this order:

  1. Environment variables;
  2. Repository: ini or .env file;
  3. default argument passed to config.
