Hi guys. I have the following code (in Python 3.7.3):

class Server:
	sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
	connections = []
	def __init__(self):
		self.sock.bind(('0.0.0.0', 10000))
		self.sock.listen(1)

	def handler(self,c,a):
		while True:
			data = c.recv(1024)
			for connection in self.connections:
				connection.send(data)
			if not data:
				print(str(a[0]) + ':' + str(a[1]), "Desconectado")
				self.connections.remove(c)
				c.close()
				break
	def run(self):
		while True:
			c,a = self.sock.accept()
			cThread = threading.Thread(target=self.handler, args=(c,a))
			cThread.daemon = True
			cThread.start()
			self.connections.append(c)

The Server code runs OK:

But the Client code does not:

I am following this Video Tutorial:



Thank you very much for your help.

sys.argv stores the values in list structure, hence to access it we have use index

###################################################################################################
### Ejecucion ###
#################
if (len(sys.argv) > 1):
    client = Client(sys.argv(1))

Modify that to, client = Client(sys.argv[1])

Thank you. Problem solved but now I get another error:

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))
