![]() The above code represents a class named “Coffee.” It has two attributes - “name” and “price” - and they’re both used in the methods. Note: All the following concepts will be explained deeper through the article. It’s only for comparing structured programming and object-oriented programming. Don’t worry if you don’t understand it yet. Let’s see the above program implemented with OOP. OOP was invented as a solution to all of these problems. This code works perfectly, but we have three problems: It’ll execute step by step, depending on your input. It’ll ask you for a budget, then “sell” you the biggest coffee you’re capable of buying. The code above acts as a coffee shop vendor. Print('Your change is', user_budget - small) Print('You can afford the regular coffee') Print('Your change is', user_budget - big) User_budget = input('What is your budget? ') Let’s see an example of structured programming with a coffee shop program. That means you’re giving the computer a list of tasks and then executing them from top to bottom. It involves running a Python program sequentially. Structured programming is the most-used paradigm by beginners because it is the simplest way to build a small program. ![]() Structured Programming vs Object-Oriented Programming This understanding leads to a rapid project initialization. Once you get some experience with OOP, you’ll be able to think of problems as small and specific objects. OOP Improves Your Analysis of Any Situation OOP gives us the possibility of compressing all the logic in objects, therefore avoiding long pieces of nested if’s. This tangle of endless lines of code is called spaghetti code, and you should avoid it as much as possible. If you keep adding features, you’ll have many nested if statements in the future. OOP Helps You Avoid Spaghetti Codeĭo you remember the number guesser program at the start of this article? ![]() You’ll see more about the abstraction principle later. Productivity decreases with not legible code It’s the reason legibility is always more important than getting features out as quickly as possible. This principle makes your code more concise and legible.Īs you may know, programmers spend much more time reading code than writing it. Object-Oriented programming allows you to reuse code by implementing abstraction. It means you can implement more features in less time without compromising the stability of a project. OOP Allows You to Code FasterĬoding faster doesn’t mean writing fewer lines of code. If you want to learn any of them after Python, it’ll be easier - you’ll find many similarities between languages working with objects. PHP (make sure to read the comparison between PHP and Python)Īll of these languages are either natively object-oriented or include options for object-oriented functionality.If you learn OOP in Python, you’ll be able to use it in the following: The following reasons will make you opt for using object-oriented programming in Python. Let’s see the main advantages of using OOP in Python. Some examples are Django, Kivy, pandas, NumPy, and TensorFlow. Many Python frameworks and libraries use this paradigm to build their codebase. OOP allows you to create secure and reliable software. Why Do We Use Object-Oriented Programming in Python? You build objects that store data and contain specific kinds of functionality. ![]() This compartmentalization is the central concept of Object-Oriented Programming. For example, consider calculators: A calculator can be an object.Īs you may notice, the data (attributes) are always nouns, while the behaviors (method) are always verbs. You can think of objects as real things around you. So when we’re talking about OOP, we’re referring to a set of concepts and patterns we use to solve problems with objects.Īn object in Python is a single collection of data (attributes) and behavior (methods). Object-Oriented Programming (OOP) is a programming paradigm in which we can think about complex problems as objects.Ī paradigm is a theory that supplies the base for solving problems. What Is Object-Oriented Programming in Python? Now you have these concepts crystal clear, you can move forward with understanding object-oriented programming. Open a Python Shell: Open a terminal and type python or python3 depending on your system.Print(number, 'is greater than the secret number') Before digging into the matter, let us pose a question: have you ever written a Python program like the one below? secret_number = 20
