# HPSocket4Python
这个是 HPSocket 的 Python 绑定，力图在 Python 上更方便的使用 HPSocket 组件。目前已经可以通过继承类的方式来使用 Tcp_Pull_Server。
代码形如：
```
# coding: utf-8

import time,sys,os
sys.path.append(os.getcwd())
sys.path.append(os.getcwd()+'\\..\\')

from HPSocket import TcpPull
from HPSocket import helper
import HPSocket.pyhpsocket as HPSocket

            print('Start server fail.')
            return False
