Confusion on class variable

class Agile: agile = True

def __init__(self, agile=True, *args, **kwargs):
    super().__init__(*args, **kwargs)
    self.agile = agile

Since we have already agile = True as class variable why is it necessary to set agile = True inisde init() ?

A class variable is shared by all instances. But "self.Agile" is an instance variable, and each instance has it's own.

Since this is implemented as an instance variable, the class variable is likely no longer needed.
