Python，socket。或没有套接字(调试帮助)

Python, socket. or no socket (Debugging help)

还在弄清楚这个python的东西。我一直在搞乱pinger协议。它还没有完全按照我的要求完成，但它正在实现。

mySocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM, icmp)
AttributeError: type object '_socketobject' has no attribute 'socket'

这是我得到的错误，问题似乎完全存在于"doOnePing"中。我还将在下面添加完整的代码，任何人都想知道其他地方发生了什么。我在用

from socket import *

谢谢您的帮助。

谢谢你的帮助。我删除了插座。当我创建我的套接字时，现在我收到了错误
