stupid
A stupid workaround when using multiple inheritance and __slots__
installation
pip install stupid
example
from hashlib import sha512
from stupid import StupidData
class User(StupidData):
name: str
class AccessData(StupidData):
access_code: sha512
class ApiPayload(User, AccessData):
pass
payload = ApiPayload("root", sha512())
payload = ApiPayload(name="root", access_code=sha512())
__slots__ are autogenerated and works with multiple inheritance as shown above.
As __slots__ are present assigning new attributes is not allowed.
>>> payload = ApiPayload(name="root", access_code=sha512())
>>> payload.extra = 1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'ApiPayload' object has no attribute 'extra'
It's also a dataclass.
>>> from dataclasses import is_dataclass
>>> is_dataclass(ApiPayload)
True
isinstance check also works.
>>> isinstance(payload, User)
True
>>> isinstance(payload, AccessData)
True
issubclass
>>> from stupid import StupidData
>>> class A(StupidData): pass
>>> class B(A): pass
>>> class C:pass
>>>
>>> issubclass(B, A)
True
>>> issubclass(B, C)
False
