Clients only receive messages after inputting

[jackfmaxwell]

Clients will only read from socket after the input is sent (since it blocks execution of loop)

Solved with threads.

sys.exit() is now exit()

Allowed users to set their username and have the server use this name when sending messages to all clients

def ReceiveMessagesThread(): while True: try: message = client_socket.recv(2048).decode('utf-8') if not len(message): print("Connection closed") exit() else: print("\n"+message)

    except IOError as e:
        continue

if name == 'main': inputThread = Thread(target=InputThread) receivingMessagesThread = Thread(target=ReceiveMessagesThread)

inputThread.start()
