In Django, how can you store static files, like CSS or JavaScript, so that they can be served efficiently?
- Embed them directly within your templates
- Place them in a directory named static within your app's directory
- Store them in the database for quick access
- Use a CDN to host the static files
In Django, you can store static files efficiently by placing them in a directory named static within your app's directory. Django's STATICFILES_DIRS setting should be configured to collect these files. This approach allows for efficient serving and easy management of static assets.
In Django, how would you extend the User model to include additional fields?
- a. Subclass the User model and add your fields to the subclass.
- b. Modify the Django source code to include additional fields in the User model.
- c. Create a separate model with a one-to-one relationship to the User model to store additional fields.
- d. It's not possible to extend the User model in Django.
In Django, you can extend the User model by creating a separate model with a one-to-one relationship to the User model to store additional fields. This approach maintains the integrity of the User model. Options a and b are not recommended as they can lead to issues during migrations and upgrades. Option d is incorrect.
In Django, the ____ file is used to store the settings of a project, such as database configurations.

Imagine you are developing a plugin system where plugins need to register themselves upon definition. How could a metaclass facilitate this registration process?
- Metaclasses can automatically register plugins by scanning the codebase for plugin classes.
- Metaclasses can create a global registry and automatically register plugins when they are defined by modifying the metaclass's __init__ method.
- Metaclasses cannot assist in plugin registration.
- Plugins can self-register by implementing a specific interface, and the metaclass can validate their registration by checking for this interface.
Metaclasses can help manage plugin registration by imposing registration checks and maintaining a central registry for plugins as they are defined.
In a ____, each element points to the next one, forming a sequence.
- Array
- Heap
- Linked List
- Stack
In a "Linked List," each element (node) contains data and a reference (or pointer) to the next node, forming a sequence. Linked lists are versatile data structures used in various applications, including dynamic data storage.
In a ____, each node contains a reference to the next node in the sequence.
- Array
- Linked List
- Queue
- Stack
A Linked List is a data structure in which each node contains a reference to the next node. This makes it a suitable choice for dynamic data structures where elements can be easily added or removed at any position.
In a binary tree, a node with no children is called a _____.
- Branch node
- Leaf node
- Root node
- Traversal
In a binary tree, a node with no children is called a "leaf node." Leaf nodes are the endpoints of the tree and have no child nodes. They are essential in various tree operations and algorithms.
