Question about implementing immutability
Let's say I want to implement immutability for user-defined class.
More precisely, a class that can be modified only in its (or its
super-class') __init__ method. My initial idea was to do it the
def __setattr__(self, *args, **kwargs):
if sys._getframe(1).f_code.co_name == '__init__':
return super().__setattr__(*args, **kwargs)
What do you think of this approach? Is there a better one?
