Hello,
I need help, with making a socket server in Python.
I have already searched google and stuff, but haven't found anything useful.
I do have found some echo server examples, but they terminate themselves, as soon, as the client leaves. Also I have found examples, what support multiple clients, but they don't work (they give me errors, when I run them).
Alse, I want to make this server with graphical user interface (gui), but I haven't understood, how to program GUI in Python.

In general i want to make asynchronous socket server with gui, rooms and stuff, running on TCP and every message terminated by zero byte ( \0 ).
Please someone help me : )
