有关从C创建Python库的建议吗？

你好?：

#include <Python.h>

static PyObject* helloworld(PyObject* self)
{
    return Py_BuildValue("s","Hello,Python extensions!!");
}

static char helloworld_docs[] =
    "helloworld( ): Any message you want to put here!!n";

static PyMethodDef helloworld_funcs[] = {
    {"helloworld",(PyCFunction)helloworld,METH_NOARGS,helloworld_docs},{NULL}
};

void inithelloworld(void)
{
    Py_InitModule3("helloworld",helloworld_funcs,"Extension module example!");
}

setup.py：

#!/usr/bin/env python

from setuptools import setup,Extension

setup(
    name='helloworld',version='1.0',ext_modules=[
        Extension('helloworld',['hello.c'])
    ]
)

建立：

$python setup.py develop
running develop
running egg_info
creating helloworld.egg-info
writing helloworld.egg-info/PKG-INFO
writing top-level names to helloworld.egg-info/top_level.txt
writing dependency_links to helloworld.egg-info/dependency_links.txt
writing manifest file 'helloworld.egg-info/SOURCES.txt'
reading manifest file 'helloworld.egg-info/SOURCES.txt'
writing manifest file 'helloworld.egg-info/SOURCES.txt'
running build_ext
building 'helloworld' extension
creating build
creating build/temp.linux-x86_64-2.7

copying build/lib.linux-x86_64-2.7/helloworld.so -> 
Creating /home/prologic/.virtualenvs/hellopyc/lib/python2.7/site-packages/helloworld.egg-link (link to .)
Adding helloworld 1.0 to easy-install.pth file

Installed /home/prologic/tmp/hello-py-c
Processing dependencies for helloworld==1.0
Finished processing dependencies for helloworld==1.0

测试：

$python
Python 2.7.6 (default,Mar 22 2014,22:59:56) 
[GCC 4.8.2] on linux2
Type "help","copyright","credits" or "license" for more information.
>>> import helloworld
>>> helloworld.helloworld()
'Hello,Python extensions!!'
>>>

祝好运！
