我有这段代码,我尝试在新线程中发送UDP数据报
import threading, socket
address = ("localhost", 9999)
def send(sock):
sock.sendto("Message", address)
print "sent"
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
threading.Thread(target=send, args=(s)).start()
但是当我尝试将套接字作为函数的参数时,会抛出一个TypeError异常:
Exception in thread Thread-1:
Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 810, in __bootstrap_inner
self.run()
File "/usr/lib/python2.7/threading.py", line 763, in
self.__target(*self.__args, **self.__kwargs)
TypeError: send() argument after * must be a sequence, not _socketobject
这意味着什么?
答案 0 :(得分:21)
您需要在变量,
之后添加逗号 - s
。只发送s到args =()试图解包一些参数,而不是只发送那个争论。
所以你有threading.Thread(target=send, args=(s,)).start()
另外,splat - *
- 运算符可能会在this问题中解释它的用法和解压缩参数
