python 中socket.error: [Errno 10022]

This error keeps appearing when using the socket module in python to change udp

The error code is posted below

server：

import socket
import random,time
s = socket.socket(socket.AF_INET , socket.SOCK_DGRAM)

host = '127.0.0.1'
port = 21567
addr = (host , port)

if __name__ == '__main__':
	s.bind(addr)
	while True:
		time.sleep(5)
		data = random.random()
		print('sendto data: %s'%str(data))
		s.sendto(str(data),addr)
	s.close()

client

	import socket
	s = socket.socket(socket.AF_INET , socket.SOCK_DGRAM)
	while True:
		data,addr = s.recvfrom(1024)
		q.put(data)
		time.sleep(random.random())

When this code is running, errno 10022 keeps appearing, and it took me an afternoon to find out 

the reason:

When a udp needs to accept data, first let the operating system know that the port where this program is located, that is, it needs to be bound

And I send data through the server, and the client receives the data. Therefore, the client does not know which port belongs to it.  

That's why this error keeps happening
