Quick Success Data Science

A hands-on guide for beginners

In the event you’re going to do any serious programming with Python, you’ll need to grasp object-oriented programming and the concept of a class and a dataclass. On this Quick Success Data Science article, you’ll get a fast and painless introduction to all three, including what they’re for, how you utilize them, and why you wish them.

Object-oriented programming (OOP) is a language model that reduces code duplication and makes code easier to update, maintain, and reuse. Consequently, most industrial software is now built using OOP.

Whereas procedural programming is built around actions and logic, OOP is built around data structures, often called objects, that consist of information and functions (called methods) that act on the information. Objects are built from classes, that are like blueprints for the objects.

A category is a data type, and once you create an object of that data type, additionally it is often called an instance of that class. The strategy of setting the initial values and behaviors of the instance is named instantiation.

As instances of a category, objects assist you to create multiple copies with the same structure but potentially different data. For instance, when you’re constructing an area combat game, you’ll be able to conveniently bundle the attributes of a certain spaceship, like its size, speed, and armament, with the methods that control its flight and weapons operation. Then, once you create a brand new spaceship of that type, you simply have to worry about giving it a novel name.

Because Python is an object-oriented programming language, you’ve already been using objects and methods defined by other people. But unlike languages reminiscent of Java, Python doesn’t force you to make use of OOP in your programs. It provides ways to encapsulate and separate abstraction layers using other approaches reminiscent of procedural or functional programming.

Having this alternative is significant. In the event you implement OOP in small programs, most of them will feel over-engineered. To paraphrase computer scientist Joe Armstrong, “The issue with object-oriented languages…
