## 1. Where should a custom Django management command file be placed to be automatically detected?

**Answer**

Custom Django management commands must be placed in the management/commands/ directory of a Django application. This directory must contain an __init__.py file in both management/ and commands/. Django automatically scans this path to discover available commands. The Python filename becomes the command name executable via manage.py.

## 2. Which base class should be used to create a custom Django management command?

**Answer**

BaseCommand is the standard base class provided by django.core.management.base for creating custom commands. It provides the necessary infrastructure: argument parsing, output color handling, error management, and integration with manage.py. The handle() method must be implemented to contain the command logic.

## 3. How to define positional arguments in a custom Django management command?

**Answer**

The add_arguments() method allows defining command arguments using the argparse parser. For positional arguments, use parser.add_argument('name') without a dash prefix. You can specify nargs for the number of expected arguments ('+' for one or more, '*' for zero or more). Arguments are then accessible via the options dictionary in handle().
