Eric Wieser <wieser.eric+py...@gmail.com> added the comment:
Not necessarily an argument against this feature, but two workarounds exist for
this already:
1. Use `nonlocal` to prevent `value` going into the class namespace:
value = None
class BaudRate(enum.Enum):
nonlocal value
for value in rates:
locals()['B%d' % value] = value
@classmethod
def valid_rate(cls, value):
return (any(value == item.value for item in cls))
2. Use `types.new_class`, which is more suited to dynamic class creation anyway:
def make_cls(ns):
for value in rates:
ns['B%d' % value] = value
@classmethod
def valid_rate(cls, value):
return (any(value == item.value for item in cls))
ns['valid_rate'] = valid_rate
types.new_class('BaudRate', (enum.Enum,), exec_body=make_cls)
