Inheritance is a fundamental concept in object-oriented programming (OOP) that allows a class to inherit attributes and methods from another class. This promotes code reusability and helps in creating a hierarchical relationship between classes. Python supports different types of inheritance, each serving a different purpose in software development. What is Inheritance? Inheritance enables a class … Read more
One of the most commonly asked questions by Python developers is: “Does Python use pass-by-value or pass-by-reference?” Does Python use pass-by-value or pass-by-reference? The answer isn’t as straightforward as it is in languages like C++ or Java. Python follows a “pass-by-object-reference” model, which is sometimes referred to as “pass-by-assignment.” This article will explore how Python … Read more
Sequential Loops vs Nested Loop Two Sequential Loops (One After Another) Nested Loop Takeway
Here are some Python hacks for competitive programming that can help you write efficient and concise code. Loops Array initialize Python does not have built-in support for arrays like other languages (C, Java), but lists can be used as dynamic arrays. Negative index in List Use defaultdict for Auto Dictionary Handling Instead of manually checking … Read more
In Python, metaclasses are a powerful and advanced feature that allows developers to control the behavior of class creation. While they may seem complex at first, understanding metaclasses can provide deep insights into Python’s object-oriented nature. What is a Metaclass? A metaclass is a class that defines how other classes behave. Just like a class … Read more
Python provides three types of methods in a class: Instance Methods, Class Methods, and Static Methods. Each serves a different purpose and is used based on the requirement. In this article, we’ll explore these methods with examples to understand their differences and use cases. Instance Methods Instance methods are the most commonly used methods in … Read more
Python provides a set of special methods, also known as dunder (double underscore) methods or magic methods, that allow developers to define how objects of a class interact with built-in functions and operators. These methods begin and end with double underscores (method) and enable customization of object behavior. Object Creation & Initialization These methods control … Read more
In FastAPI, templates are commonly used to render HTML pages dynamically. FastAPI supports templates through libraries like Jinja2, which allows you to inject dynamic content into HTML files. Installing Jinja2 Setting Up Templates in FastAPI You need to use Jinja2Templates from fastapi.templating and set up a templates directory. Project Structure Example Creating Template Files Inside … Read more
FastAPI is a high-performance web framework that simplifies building APIs with Python. One of its most powerful features is middleware, which allows developers to modify requests and responses globally before they reach the route handlers. What is Middleware? Middleware is a function that runs before and after every request in FastAPI. It can: FastAPI uses … Read more
Pydantic is a powerful Python library for data validation and settings management. It is particularly popular in modern Python applications because it can enforce data correctness using Python-type hints. This makes it an essential tool for backend developers, especially those working with APIs and data processing tasks. Why Use Pydantic? Getting Started with Pydantic Installation … Read more
