python - 套接字上的 AttributeError

Question

from socket import socket, AF_INET, SOCK_DGRAM
import struct
import sys
import time

TIME1970 = 2208988800L  

client = socket.socket( socket.AF_INET, socket.SOCK_DGRAM )
data = '\x1b' + 47 * '\0'
client.sendto( data, ( sys.argv[1], 123 ))
data, address = client.recvfrom( 1024 )
if data:
    print 'Response received from:', address
    t = struct.unpack( '!12I', data )[10]
    t = TIME1970
    print '\tTime=%s' % time.ctime(t)

当我尝试执行此脚本时，出现以下错误；请在这件事上给予我帮助：

File "C:\Users\Wolverine\Desktop\Apcog-python prog\test.py", line 8, in ?
    client = socket.socket( socket.AF_INET, socket.SOCK_DGRAM )
AttributeError: socket
Traceback (innermost last):

    client = socket.socket( socket.AF_INET, socket.SOCK_DGRAM )
AttributeError: socket

Answer 1

您导入socket了 asfrom socket import socket以及该模块中的其他元素，因此您不需要使用模块名称来引用它：

client = socket(AF_INET, SOCK_DGRAM)

或者，将导入行更改为：

import socket

并继续通过属性访问引用该模块中的项目。
