python - 当发生套接字错误时，如何从异常中获取其错误代码？

Question

像这样的代码:

import socket, sys

try:
    address = ('127.0.0.1', 31500)  
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
    s.connect(address)  
except Exception:
    errType, errValue, errTraceback = sys.exc_info()
    # or
    # handle the Exception it throw out ?

我想要得到的是类似10060的错误代码，这意味着connection time out，感谢您的帮助:)
