python socket programming OSError: [WinError 10038] an operation was attempted on something that is not a socket

Question

I am working on this code

from socket import *
HOST = 'localhost'
PORT = 21567
BUFSIZ = 1024
ADDR = (HOST, PORT)
serversock = socket(AF_INET, SOCK_STREAM)
serversock.bind(ADDR)
serversock.listen(2)

while 1:
    print ("waiting on connection")
    clientsock, addr = serversock.accept()
    print ('connected from:', addr)
    while 1:
        data = clientsock.recv(1024).decode()
        if not data: break 
        clientsock.send(data.encode())
        clientsock.close()

serversock.close()

I get this error:

OSError: [WinError 10038] an operation was attempted on something that is not a socket

Answer 1

You are closing the clientsock after reading only part of the data.

clientsock.close()

is at the wrong level of indentation. Move it to the left by one step.

Answer 2

The problem is with close(). after connection get close you need to initialize the connection again

add this line inside while loop

serversock = socket(AF_INET, SOCK_STREAM)
