# metaprepare.py
class Meta1(type):
@classmethod
def __prepare__(mcs, name, bases):
print('call prepare')
return {}
def __new__(mcs, name, bases, parameters):
return super().__new__(mcs, name, bases, parameters)
class A(metaclass=Meta1):
pass
type('C', (A, ), {})
output is:
call prepare
(just the once, not twice)
The behavior of `type()` not calling `__prepare__()` has been constant since
3.3.
Is it a bug?
