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):
		pass

	def _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 hosts

	def 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：
