You can use the SimpleHTTPRequestHandler class to serve static files from a directory. Python’s built-in http.server module can be used to create a basic HTTP server. The class that inherits is called the subclass, and the class being inherited from is called the superclass. It’s used to add custom or third-party module locations to the import search path.
NoSQL (Not Only SQL) databases are non-relational databases that store data using models such as documents, key-value pairs, wide columns, or graphs rather than traditional relational tables. Django connects to databases through the configuration defined in the settings.py file. Media Root is the directory where user-uploaded files (media files) are stored. For example, when a new user is created, a signal can be used to automatically create a corresponding profile.
Using async def to declare https://uvik.io/ asynchronous functions paired with await to pause execution until results are ready. Lists, tuples, dictionaries, and sets are core data structures providing efficient ways to store, retrieve, and manipulate collections of data. Lambda functions are anonymous, single-expression functions defined using the lambda keyword. Generators are special iterators defined with functions using the yield keyword.
What is the difference between deepcopy and shallow copy in Python?
- Your experience, past projects, familiarity with various Python libraries, and problem-solving skills may all be questioned by the interviewer.
- Binding or wrapping of code and data together into a single cell is called encapsulation.
- React Router is a routing library for React that enables navigation between different components or pages in a single-page application (SPA).
- If choices are given, they’re enforced by model validation and the default form widget will be a select box with these choices instead of the standard text field.
The parent module coordinates the build process and manages the dependencies between the child modules. A Spring Boot Multi-Module Project is a project structure where We organize Wer codebase into multiple modules, each representing a different functional or logical unit of Wer application. But, if object type is converted/type-casted an instance of stdClass is created, if it is not NULL. The Model-View-Controller (MVC) framework is an architectural/design pattern that separates an application into three main logical components Model, View, and Controller. This is done via a Python module called URLConf (URL configuration). Django lets us interact with its database models, i.e. add, delete, modify, and query objects, using a database-abstraction API called ORM(Object Relational Mapper).
FastAPI provides a simple way to handle file uploads using the File and UploadFile classes. Then, a Pydantic model is created to handle data validation and serialization. First, a SQLAlchemy model is defined for the database structure. FastAPI provides a security module to implement authentication and authorization. Pydantic models define how requests and responses should be structured, enabling automatic request body parsing, validation, serialization, and documentation. It ensures that incoming data matches the expected types, reducing runtime errors.
Conditional rendering is a technique in React that displays different UI components or elements based on a condition. In Node.js, files are read and written using the built-in fs (File System) module. JavaScript provides several looping structures to execute a block of code repeatedly based on a condition or iterable. An image can be centered horizontally and vertically using CSS, with Flexbox being the simplest and most commonly used approach. It continues track changes made to these files over time, helping teams work together evenly. Lists in React are created by using the map() method to render multiple elements from an array.
