Python: TypeError: argument after * must be a sequence

Question

I have this piece of code in which I try to send an UDP datagram in a new thread

import threading, socket

address = (\"localhost\", 9999)


def send(sock):
             


        

Answer 1

You need to add a comma - , - after your variable s. Sending just s to args=() is trying to unpack a number of arguments instead of sending just that single arguement.

So you'd have threading.Thread(target=send, args=(s,)).start()

Also the splat - * - operator might be useful in this question explaining it's usage and unzipping arguments in general
