You are creating an instance of class Client with one argument

client = Client(sys.argv[1])

And your Client class initialization is defined as:

class Client:
    def __init__(self):
        self.sock.connect((address, 10000))

It seems you want to create the Client instance with the IP address
so the __init__ needs to be modified:

class Client:
    def __init__(self, address):
        self.sock.connect((address, 10000))
