future
provides a function (from jinja2/_compat.py
) called
with_metaclass()
that can assist with specifying metaclasses
portably across Py3 and Py2. Use it like this:
from future.utils import with_metaclass
class BaseForm(object):
pass
class FormType(type):
pass
class Form(with_metaclass(FormType, BaseForm)):
pass
