Sockets python client

I currently have this code

import socket
server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
ip = socket.gethostbyname(socket.gethostname())
port = 1111
address=(ip,port)
server.bind(address)
server.listen(1)
print("Started listening on", ip, ":", port)
client.addr=server.accept()
while True:
      data = client.recv(1024)
      print("received",data, "from the client")
      print("Processing data")
      if(data=="Hello server"):
          client.send("hello client")
          print("Processing done")
      elif(data=="disconnect"):
          client.send("goodbye")
          client.close()
          break
      else:
          client.send("Invalid data")
          print("invalid data")

However i get this error message: NameError: name 'client' is not defined. But why?

Well, that is devoted to the fact that the function server.accept() return two values, the socket itself and the address. Therefore being accepted this way:

client, addr = server.accept()

would allow what you are trying to achieve.
