# Cleanup os.remove('.env') os.remove('.env.local')
# .gitignore .env.python.local
The python-env-loader package takes this pattern further by automatically handling priority between .env and .env.local files, similar to how Create React App handles environment variables.
. This is the most critical rule of environment variable management. When real API keys or database credentials are committed to a public repository, automated bots scan continuously for them and can exploit them within minutes, leading to potentially costly security breaches.
: In custom loading scripts, it is typically designed to override values found in a standard .env or .env.development file. .env.python.local
: Contains safe, shared, or default configurations (shared with team).
# Environment files (DO NOT commit actual .env files) .env .env.local .env.python.local .env.production .env.* !.env.example
Which you are using (e.g., FastAPI , Django , or Flask )?
This occurs because the file was indexed by Git before its addition to .gitignore . Clear the tracking cache by running: # Cleanup os
load_dotenv('.env.python.local')
Now go forth, brave coder, and let .env.python.local bring peace to your projects. 🌦️🐍
If you would like to expand this configuration setup, please let me know:
In modern software development, hardcoding configuration data—such as API keys, database URLs, or secret keys—directly into your source code is a major security risk and a violation of the 12-Factor App methodology. When real API keys or database credentials are
database_url = os.getenv("DATABASE_URL") if not database_url: raise ValueError("DATABASE_URL environment variable is required")
The .env.python.local file is more than just a filename—it's a philosophy of environment-aware configuration. It respects that no two development environments are identical. It honors the principle of least surprise by giving local settings the highest priority. And most importantly, it keeps secrets out of your repository.
# .env.example DATABASE_URL=postgresql://localhost/myapp SECRET_KEY=your-secret-key-here DEBUG=false EXTERNAL_API_KEY=your-api-key
