How to add arguments in brackets?

Question

Python

Hello.
I saw something like this entry
import serverSocket
server = serverSocket.TCPserver(("", 8000), handler...)
When is such an entry in brackets used as a separate argument and how is it created in the class that two arguments will be accepted, like one separate?
Is it possible, with an example, please.

Answer 1

This is called a tuple . Usually this data type is described in the very first chapter of any textbook.
