cry: 你好!

借鉴其他语言的异常思想,不是这样写捕获语句的.
你的捕获机制不完善,导致你漏掉了一些异常.

建议你的异常捕获象下面这样分级捕获, 每个异常捕获语句仅捕获自己感兴趣的异常,
最后使用Exception捕获所有未拦截的异常.

import httplib
import socket

try:
    conn = httplib.HTTPConnection("127.0.0.1:8080")
    conn.request("GET", "/")
    response = conn.getresponse()
    result = response.read()
    print result
    conn.close()

except socket.error, msg:
    print msg
    # do something other

except httplib.HTTPException,msg:
    print msg
    # do something other

except Exception, msg:
    print msg
    # do something other

limodou，您好！

直接用except:当然是没有问题，但是我需要错误信息呀，比如：
except error,msg:
