python - How to fix - TypeError: can't set attributes of built-in/extension type 'set'

Question

I'm relatively new to python and I'm trying to make a simple GUI chat with python. It is programmed to ask for a nickname when a client joins the server. All works fine until the part where I enter the nickname. When I enter the nickname I get these errors from the server and client respectively, I'll provide the tracebacks as well.

ConnectionResetError: [Errno 104] Connection reset by peer (From server)

traceback:

Traceback (most recent call last):
  File "server.py", line 51, in <module>
    receive()
  File "server.py", line 44, in receive
    broadcast(f"{nickname} entered to the chat!
".encode('utf-8'))
  File "server.py", line 17, in broadcast
    client.send(message)

TypeError: can't set attributes of built-in/extension type 'set' (from client)

traceback:

Traceback (most recent call last):
  File "C:/Users/ISINDU WICKRAMASEKAR/PycharmProjects/guichat/client.py", line 94, in <module>
    client = Client(HOST, PORT)
  File "C:/Users/ISINDU WICKRAMASEKAR/PycharmProjects/guichat/client.py", line 22, in __init__
    set.gui_done = False

The code for the server and client are also linked.

What I have tried:

I tried googling for answers and I can't say I didn't get any, but I didn't understand how to implement those solutions for my issue. These are the links I referred to

1. Python handling socket.error: [Errno 104] Connection reset by peer

2. python can't set attributes of built-in/extension type 'object'

Answer 1

I think the error message points us to the problem pretty precisely.

Traceback (most recent call last):
  File "C:/Users/ISINDU WICKRAMASEKAR/PycharmProjects/guichat/client.py", line 94, in <module>
    client = Client(HOST, PORT)
  File "C:/Users/ISINDU WICKRAMASEKAR/PycharmProjects/guichat/client.py", line 22, in __init__
    set.gui_done = False
TypeError: can't set attributes of built-in/extension type 'set' (from client)

On line 22 of client.py, you try to assign set.gui_done = False; you probably meant self.gui_done.
