查询属性名称及其 class

Question

可以用__name__询问属性的名称。不过，我也想查询一下class的名字：

class Test:
    __slots__ = ['a', 'b']

print(Test.a.__name__) # → 'a' but wanted 'Test.a' or only the class 'Test'

Answer 1

听起来你想要 __qualname__。

class Test:
    __slots__ = ['a', 'b']

Test.a.__qualname__
# gives 'Test.a'

Is there also a magic method of getting the class name only?

您可以通过 Test.a.__objclass__ 获取 class 本身。所以 class 的名称可以通过

获得

Test.a.__objclass__.__name__
# gives 'Test'

Query attribute name together with its class
