this is the client of the instance

from socket import *

HOST="localhost"
PORT=10001
BUFFER=1024
ADDRESS=(HOST,PORT)

clientSocet=socket(AF_INET,SOCK_STREAM)
clientSocet.connect(ADDRESS)
while True:
    data=input(">")
    if not data:
        break
    clientSocet.send(data.encode())
    data=clientSocet.recv(BUFFER).decode()
    if not data:
        break
    print(data)
clientSocet.close()
