Explain with highlit
I organize settings into base, development, and production modules. The base contains common settings, while dev and prod override specific values. I use environment variables for secrets via os.environ.get() or python-decouple. The django-environ package simplifies this with .env files. For different environments, I set DJANGO_SETTINGS_MODULE to the appropriate module. I keep sensitive settings out of version control using .env.example as a template. This approach makes deployments predictable and secure, with clear separation between local and production configs.
