Can not access variable from an instance of a class in python

Question

I have declared a variable of a class in the def __init__() but when I create an instance of that class and try to access one of the variables I created it says "object has no attribute"

from pyglet.gl import *
from pyglet.window import Window
from Renderer import Renderer


class Window(Window):

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.renderer = Renderer()
        self.test = 1
        glClearColor(255, 0, 0, 255)

window = pyglet.window.Window(400, 300, "Window", resizable=True)
print(window.test)

Renderer is a class I've made, but pyglet is a library

The problem here is that I can't access window.renderer, nor window.test.

Error: AttributeError: 'Win32Window' object has no attribute 'test' How can I solve this?

Hello and welcome to StackOverflow! Would you mind posting the entire traceback? — Daniel Walker

It doesn't look like you are making an instance of your window class. You are making an instance of pyglet.window.Window — Mark

@DanielWalker Thank you for the reply :) ```Traceback (most recent call last): File "D:/Users/user/Projects/Python/Project/Window.py", line 15, in <module> print(window.test) AttributeError: 'Win32Window' object has no attribute 'test' — ertemo

@MarkMeyer Thank you so much! I completely forgot to remove the pyglet.window :) — ertemo

do not name classes the same as the classes you inherit, as this might cause issues further down the line. Especially if you want to create two windows. either do Window(pyglet.window.Window) and import pyglet with import pyglet instead of from pyglet.window import Window. Or rename your class to MyWindow(Window) instead. As you're replacing the imported Window otherwise. — Torxed

window = Window(400, 300, "Window", resizable=True)

would create an instance of your custom Window.
