Why did you define class variable and instance variable with the same name- sneaky? Isn't it that the instance variable shadows the class variable? If so, the class variable has no actual meaning.

# a simple class with one attribute
class ClassOne:
color = "white"
def __init__(self, color, **kwargs):
self.color = color
for key, value in kwargs.items():
setattr(self, key, value)
>>> c = ClassOne("red")
>>> c.color
"red"
>>> del c.color # delete instance attribute
>>> c.color
"white"
>>> ClassOne.color
"white"
