? How to Use .env Files in Python Using the python-decouple Module ?

Managing configuration settings in Python projects is a common challenge. Hardcoding sensitive information or settings in your code is a security risk, and manually configuring settings for different environments can be cumbersome. Enter the python-decouple module, a convenient solution for handling configuration parameters stored in .env files. Let's explore how to use it effectively in your Python projects.

1. Installation: Start by installing the python-decouple module using pip:

pip install python-decouple

2. Creating a .env File: Create a .env file in the root of your project directory. This file will store your configuration parameters. For example:

user=rohit
pwd=sharma

3. Importing and Using Config: In your Python script, import and use the Config class from decouple. Access the configuration parameters using the config object:

from decouple import config

user = config('user')
pwd = config('pwd')


4. Secure .env Handling: Ensure that your .env file is not checked into version control systems to keep sensitive data safe.

By using the python-decouple module and .env files, you can centralize and manage your project's configuration parameters easily. This approach enhances security, simplifies environment-specific configurations, and promotes clean, maintainable code.
