Python Magic Methods with Stock Sorting
Python Magic Methods with a Stock Sorting Example Python magic methods, also known as “dunder” methods (short for “double underscore”), allow us to define how custom objects behave in specific situations. Two of the most commonly used magic methods are __str__ and __lt__. In this blog, we’ll explore how these methods can be used to […]
Sorting Stocks and Bonds in Python
Sorting Stocks and Bonds in Python In this programming challenge, we’re tasked with building on a previously developed codebase, adding new functionality to manage stocks and bonds in a more Pythonic way. Specifically, we’re going to implement sorting logic for these financial assets based on different criteria: stocks will be sorted by their price, and […]
Using the __call__ Magic Method in Python
In Python, everything is an object, including functions. But what if you could make any object behave like a function? That’s where the __call__ magic method comes in. This special method allows an instance of a class to be called as if it were a function, adding a layer of flexibility and control to how […]
Attribute Access with Python’s Magic Methods
Python’s magic methods offer a powerful way to control how attributes are accessed and modified in your classes. By overriding these methods, you can customize the behavior of attribute retrieval and assignment, giving you greater flexibility in how your objects interact with the rest of your code. In this post, we’ll explore three key magic […]
Python Classes with Comparison Magic Methods
In Python, custom objects don’t know how to compare themselves with other objects out-of-the-box. By default, two different instances of a class will be considered unequal unless explicitly instructed otherwise. However, Python offers a way to define custom comparison behavior using magic methods. In this blog post, we’ll explore how to implement comparison methods in […]
String Representation in Python with Magic Methods
In Python, understanding how to customize the string representation of objects is an essential skill, particularly when working with object-oriented programming. Python provides two key magic methods, __str__ and __repr__, that allow you to control how your objects are represented as strings. These methods are invoked automatically by Python in different contexts, such as when […]
Understanding Python’s Magic Methods
In Python, magic methods, also known as dunder methods (because they begin and end with double underscores), are a set of predefined methods that allow you to define the behavior of your objects in a variety of situations. These methods are automatically associated with every class definition, and by overriding them, you can customize how […]
Solution Overview Stocks and Bonds
In a previous challenge, we explored how to represent financial assets like stocks and bonds using inheritance in Python. This blog post reviews a solution to that challenge, where we created a class structure that leverages inheritance to group common properties while ensuring that subclasses implement specific behaviors. Let’s dive into the solution and see […]
Stocks and Bonds with Inheritance
In this blog post, we’ll tackle an interesting programming challenge that involves creating a class structure using inheritance to represent both stocks and bonds. This exercise will help you understand the concept of inheritance, abstract base classes, and how to design a class hierarchy in Python. The Challenge The goal of this challenge is to […]
Composition in Python
In the world of object-oriented programming, two fundamental concepts for building complex systems are inheritance and composition. While inheritance models an “is-a” relationship, composition models a “has-a” relationship. This blog post explores the concept of composition in Python, demonstrating how to create complex objects from simpler ones, thereby making your code more modular and maintainable. […]
