In Django, you can check if the DEBUG setting is True by using the following code:

​

Copy code

from django.conf import settings

​

if settings.DEBUG:

    # DEBUG is True

else:

    # DEBUG is False

The DEBUG setting is a boolean value that indicates whether Django is in debug mode or not. When DEBUG is True, Django will display detailed error pages and enable additional debugging features. When DEBUG is False, Django will display a generic error page and disable debugging features.

​

It is generally a good practice to set DEBUG to False in production environments to ensure that sensitive information is not accidentally leaked and to prevent security vulnerabilities.

​

Note that the value of DEBUG can be set in the Django settings file (typically settings.py). By default, DEBUG is set to True when you run Django in development mode, and False when you run Django in production mode.
