How can I use python-dotenv in my Flask application?

You can use python-dotenv to load environment variables from a .env file into your Flask app. First, install it using pip.

What should I include in my .env file?

Your .env file should include key-value pairs for your configuration, like SECRET_KEY and DATABASE_URL.

How do I access these variables in my Flask app?

You can access them using os.getenv('VARIABLE_NAME') after loading dotenv in your app.

Can you show me a code example?

Sure! Here's a simple example:

from flask import Flask
from dotenv import load_dotenv
import os

load_dotenv()

app = Flask(__name__)
app.config['SECRET_KEY'] = os.getenv('SECRET_KEY')
