Python/capi:创建“\uu all\uuuj”对象

Question

在使用普通Python3创建Python模块/库时，我可以轻松地创建__all__列表。然后，在导入模块之后，我可以通过“MODULE.__all__”访问它。你知道吗

但是，在通过Python/capi创建模块时，我无法找到一种简单或“适当”的方法来生成__all__。我查阅了官方文件，没有找到答案。你知道吗

在使用Python/capi制作的模块中创建__all__是否有一种简单的方法或标准方法？你知道吗

我可以使用下面的代码创建类似的对象（比如__author__）。你知道吗

static const char __author__[32] = "Devyn Collier Johnson";
static const char __copyright__[8] = "LGPLv3";
static const char __version__[16] = "2015.11.21";
PyModule_AddStringConstant(m, "__author__", __author__);
PyModule_AddStringConstant(m, "__copyright__", __copyright__);
PyModule_AddStringConstant(m, "__version__", __version__);

下面是我的一个特定模块的代码（为了便于阅读，我删除了函数和大块注释）

#include <Python.h>

#include "geometry.h"


static const char __author__[32] = "Devyn Collier Johnson";

static const char __copyright__[8] = "LGPLv3";

static const char __version__[16] = "2015.11.21";

static const char __all__[16][32] = {
    // Distance
    "distance",
    "linelength",
    // Area
    "areacircle",
    "areasquare",
    "areasquare_int",
    "areasquare_shape"
};


// Docstrings

static char module_docstring[32] =
    "Geometry Equations";
PyDoc_STRVAR(geometry_distance_docstring,
    "distance(location1: tuple, location2: tuple) -> float\nReturn the distance between two points");
PyDoc_STRVAR(geometry_linelength_docstring,
    "linelength(location1: tuple, location2: tuple) -> float\nReturn the length of a line (given two points as tuples with two floats each)");
PyDoc_STRVAR(geometry_areacircle_docstring,
    "areacircle(radius: float) -> float\nReturn the area of a circle (float)");
PyDoc_STRVAR(geometry_areasquare_docstring,
    "areasquare(length: float) -> float\nReturn the area of a square (float)");
PyDoc_STRVAR(geometry_areasquare_int_docstring,
    "areasquare_int(length: int) -> int\nReturn the area of a square (int)");
PyDoc_STRVAR(geometry_areasquare_shape_docstring,
    "areasquare_shape(square: float) -> float\nReturn the area of a square (float)");
