What could be the server problem and how to solve it?

Question

Python

I just started to learn the socket module and decided to try to make a local server, and at the first start the problems started. Here is the code

import socket
server = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
server.bind(("127.0.0.1", 21356))
server.listen()
while True:
    user, adres = server.accept()

turned off the firewall, the antivirus too, but such an error comes out, the

question may seem silly and simple, but it’s really not clear to me what could be the problem

Answer 1

UDP sockets do not use listen()/accept().
You can immediately do socket.recvfrom()
