I am a rookie who tries to learn OOP in python. For the sake of learning and practice, I am working on a task that asks me to create a transaction method in the class BankAccount that transfers money from one bank account to another. Here is the code I have written so far: class ..

Creating a space invaders style game using sprites as a pose to images – Trying to get the bullet to continually move up the screen until it detects that it’s passed y = 0. I’ve got an function to fire that moves the bullet up, but only by 5 pixels per MOUSEBUTTONDOWN event detected. Ideally, ..
I’ve tested this snippet and get the result as expected: import requests import json url = ‘https://example.com/getlistitem’ headers= { ‘User-Agent’: ‘Mozilla/5.0’, ‘Referer’: ‘http://banggia.tvs.vn/’, ‘content-type’: ‘text/json’, ‘Content-Type’: ‘application/json;charset=utf-8’ } res=requests.get(url, headers = headers, timeout= 30).json() print(res) Now, I manage to convert it into class as this: class getvps(): url = ‘https://example.com/getlistitem’ headers= { ‘User-Agent’: ‘Mozilla/5.0’, ‘Referer’: ..
Context I am creating a game in Python using pygame to apply SOLID principles and MVC concepts that I self-studied. I once had a class that, I think, has more than one responsibility (Move by changing position, change movement angle/direction, reacts to user input, fire, damage entity, etc.). So I decomposed that class into the ..
I’m reading Mark Summerfield’s Programming in Python 3 book. In the chapter on OOP, he uses the below Circle class to demonstrate inheritance. Regarding the __eq__ method, he states: "This method compares this circle’s radius with the other circle’s radius and if they are equal it then explicitly call’s the base class’s __eq__ method using ..
I have been trying to understand why the .get_or_create function I’m using isn’t working. It’s supposed to find the object in the DB with matching parameters and create a new one if none are found. When running this, it always says that there are not matching objects and the tuple return True every time hence ..
I have an example class like so: class Foo: __attr: tuple[type, type] def __init__(self, ty: type): __attr = (Foo, ty) def validate(self, ty: type) -> bool: return ty in Foo.__attr @staticmethod def Attr() -> tuple[type, type]: return Foo.__attr The getter here is so that the private class variable can still be read from outside the ..
I am a student who tries to learn OOP in python and in general, and for the sake of practice, I am writing a class that makes right triangles and calculates their hypotenuse using the Pythagoras theorem. A pretty straightforward program, but it revealed that I have some practice to do when it comes to ..
I was working on a game using the pygame library on Python. I basically defined a Character class from which the Knight class and Enemy class would inherit functions. Since both children classes use the same initialize functions, I defined the init function under the parent class. However, I don’t fully understand how it works ..
I’m just getting into OOP in Python and struggling with classes. Basically I’m creating a method that needs to find the Euclidean distance between two points. I’ve created a method that creates the two points, it works. I’ve then created a method __sub__ that subtracts from those two points with another point instance, it then ..
