C语言调用python

一，安装环境sudo apt install libpython3.10-dev,安装C代码调用python的库函数和动态库

#include "Python.h"
int main()
{Py_Initialize(); // 初始化python解释器PyRun_SimpleString("print ('funny')");//在C语言调用print()打印字符串Py_Finalize(); //释放python解释器占用的资源return 0;
}

二、调用无参函数

#include<Python.h>int main()
{Py_Initialize();PyObject *sys =PyImport_ImportModule("sys");PyObject *path = PyObject_GetAttrString(sys, "path");PyList_Append(path,PyUnicode_FromString("."));PyObject *pModule = PyImport_ImportModule("nopara");PyObject *pFunc = PyObject_GetAttrString(pModule, "say_funny");PyObject *pValue = PyObject_CallObject(pFunc, NULL);// 释放所有引用的Python对象Py_DECREF(pValue);Py_DECREF(pFunc);Py_DECREF(pModule); Py_Finalize();return 0;
}

PyObject_CallObject(pFunc, NULL);无参调用函数
