从 C++ 中查找 python 函数参数

#include<Python.h>

int main() {
    PyObject* pModuleName;
    PyObject* pModule;
    PyObject* pFunc;
    PyObject* pArgs;
    PyObject* pValue;

    Py_Initialize();

    pModuleName = PyUnicode_FromString("my_module");
    pModule = PyImport_Import(pModuleName);
    Py_DECREF(pModuleName);

    pFunc = PyObject_GetAttrString(pModule, "my_function");

    pArgs = PyTuple_New(2);
    PyTuple_SetItem(pArgs, 0, PyLong_FromLong(1));
    PyTuple_SetItem(pArgs, 1, PyUnicode_FromString("Hello, world!"));

    pValue = PyObject_CallObject(pFunc, pArgs);
    Py_DECREF(pArgs);

    if (pValue == NULL) {
        PyErr_Print();
        fprintf(stderr, "Call failed\n");
        return 1;
    }

    Py_DECREF(pValue);
    Py_DECREF(pFunc);
    Py_DECREF(pModule);

    Py_FinalizeEx();

    return 0;
}
