Python C API中的静态变量 [英] Static Variables in Python C API

问题描述

如何暴露这样的静态"变量

How would one expose "static" variables like this

class MyClass:
    X = 1
    Y = 2

通过C API? PyTypeObject上唯一看起来正常工作的变量是tp_members，但我看不到PyMemberDef中的标志来指示该成员应按类而不是按实例.

via the C API? The only variable on the PyTypeObject that looks like it would work is tp_members, but I see no flag in the PyMemberDef to indicate that the member should be per-class, not per-instance.

需要更多说明，因为它可能会改变答案，所以我试图向Python公开C枚举，以便枚举

For a bit more clarification, since it may change the answer, I'm trying to expose a C enum to Python such that the enumeration

enum MyFlags {
    Alpha = 0,
    Beta = 1
};

可以在Python中以以下方式访问:

Can be accessed in Python as:

module.MyFlags.Alpha
module.MyFlags.Beta

推荐答案

只需将它们放入类型的 tp_dict 例如与 PyDict_SetItemString .

Just put them in the type's tp_dict e.g. with PyDict_SetItemString.
