OOP with Pygame - Object Oriented Programming Exercise

Показать описание

Welcome to another Python Object Oriented Programming exercise! Where we will practice classes, objects, attributes, methods, and inheritance using Pygame 🐍🐍🐍
We will take an image of a car, turn it into an object, and use it to generate trucks, police vehicles, and all kinds of sedans. The purpose of this tutorial is to help you understand the different aspects of OOP and show you why it's such an important programming concept.
Even though this video begins with a quick refresher, it is recommended for folks who already have a basic background with Python classes. If you are an absolute beginner, please refer to the two tutorial recommendations on the screen and in the links below.

You are declaring instance attributes outside of the __init__ method, which is not ideal. You can just create them with a value of None, and then set them in the draw method. If you never call the draw method, that means the attributes will never be initialized (set) and thus, do not exist.

Thank you so much. That replacing "self" with "vehicle" really cleared a lot of things

Visuals are very important when learning, for a lot of people. This was a great way to show off classes and although I have been using Python a while, I feel a lot more comfortable with some things I did not know before (like the super required in inheritance!) Fantastic video!

Thank you! You're a great explainer! You seem like you test your tutorials ahead, so you don't get tripped up on small details like many do when doing tutorials.

You are such a perfect teacher. So easy to understand you. Even though I am more of a Java, c and c++ developer.

Good morning! I'm enjoying learning from such a skilled little snake charmer. Please feel free to keep sending those homework assignments my way - practice makes python! Thank you Mariya! 😊😃😛😉

Спасибо, Маша! Отлично обхяснила. Даже я что-то понял из ООП. Пожалуй вернусь к этому упражнению после прохождения курса по ООП на степике!

This is great! Going to rewatch later when I get on my computer...

Woow best OOP lesson that i have ever seen. 🥰

I really love your content- you have a gift for teaching thank you for sharing

Thank you for continued content. Would love a video that goes over how how to self-learn new python modules! Ideas would include how to get used to reading python module documentation, what to google, how to find examples etc.., how to start playing with a new module etc..

Hope you respond whether you think this is a good or bad idea/or any thoughts in general. Thanks!

In pygame or python ursina or cave engine it is more effective to write the classes like "class MY_CLASS(WHAT_MY_IS):". The reason: Game engines like Ursina, PyGame or Cave call predefined instances such as “Entity”, “Text”, “Animation” or simple “Scene”. This means that if you write larger code, sooner or later type problems will arise when recognizing and reading the instances if this is not stated directly. At the same time, these are able to use the update definition with the delta time and update themselves. If you don't specify anything there, the update function will only work to a limited extent there or at least only if you integrate it somewhere else, which will end up eating up a lot of performance and Python is a bit slower in gaming anyway. It would also make the code easier to understand and read if you use variables or values that are as short as possible than the actual string or value itself. Example: instead of

xEndless

I know it's a tutorial (a very good one to say), but as an OOP Coder I don't feel good with deep inheritances and something that may break the Liskov substitution principle. So to create a "class DrawableItem" and inherit from this would make more sense in practice than to create a class Car/Vehicle and class Truck(Vehicle). In practice it would make more sense most of the time to use composition instead of inheritance.
