I want to change the value of attribute
View class permanently when I call
changeColor method and the value still permenant unless I call the method again with another color,
when I call
changeColor method the
pen_color attribute still have the same value and I don’t want such thing
Is there any way to do such thing or not ?
class View: def __init__(self): self.pen_color = 'red' class Button(View): def __init__(self): pass def changeColor(self): super().__init__() self.pen_color = 'green'
You should move the declaration of pen color into a class attribute rather than an instance attribute and reference it as
Having done that
View.pen_color will be permanent and global, but can be shadowed by
self.pen_color in either View or Button instances.
