c++ 调用 python 实例 涉及 类 多参数 列表作为参数

1个解析ip的python代码，文件名为ipParser.py

class IPParser:def __init__(self):passdef _parse_ip( self, line ):segs = line.split(".")if len(segs) != 4:return (False,"Invalid input format : %s" %(line))cells = []for seg in segs:cell = []for i in seg.split(","):if '-' not in i:cell.append(i)else:start,end = i.split("-")cell +=  [ str(i) for i in range( int(start), int(end) + 1)]cells.append(cell)hosts = []for s0 in cells[0]:for s1 in cells[1]:for s2 in cells[2]:for s3 in cells[3]:host = ".".join([s0,s1,s2,s3])hosts.append(host)return hostsdef parse_ip( self, lines ):    hosts = []    for line in lines:    for sub_line in line.split(" "):     hosts += self._parse_ip(sub_line)    return hosts

1个公共使用的python代码,文件名为shareFun.py

def parseStr(s,delimiter):return s.split(delimiter)

下面是c++代码

void TestMultiArgsAndClass(){Py_Initialize();//****************下面引用shareFun.py的代码PyObject *pModule =PyImport_ImportModule("shareFun");//导入py模块PyObject *pFunc= PyObject_GetAttrString(pModule, "parseStr"); //引入py模块中的函数//建立形参PyObject *pArgs = PyTuple_New(2); PyTuple_SetItem(pArgs, 0, Py_BuildValue("s", "10.0.1.1-10;10.0.2.11-13"));PyTuple_SetItem(pArgs, 1, Py_BuildValue("s", ";"));//说明： py模块中的parseStr函数的形参为两个str，这里传递的pArgs是元组，原因是PyEval_CallObject的第2形参的格式要求；PyObject *pReturn = PyEval_CallObject(pFunc, pArgs);//调用函数//***************下面引用ipParser.py的代码PyObject * pModule2 =PyImport_ImportModule("ipParser");PyObject *pClassIpParser = PyObject_GetAttrString(pModule2, "IPParser");//上面两个步骤与导入shareFun.py步骤相同//类的实例PyObject *pInstanceIpParser = PyInstance_New(pClassIpParser, NULL, NULL);//调用类对象pInstanceIpParser的parse_ip方法，形参为pReturn   // Py_BuildValue("s","parse_ip")  将c字符串转为python字符串PyObject * prrr = PyObject_CallMethodObjArgs(pInstanceIpParser, Py_BuildValue("s","parse_ip"), pReturn,NULL); //处理返回值:int size = PyList_Size(prrr);//prrr 为列表cout << "返回列表的大小为: " << size << endl;for(int i=0;i<size;++i){PyObject *pNewAge = PyList_GetItem(prrr,i);//相当于 python中的prrr[i]char *  newAge;PyArg_Parse(pNewAge, "s", &newAge);//将python的字符串转为c字符串cout << newAge << endl;}Py_Finalize();}

结果：
