DESCRIPTION¶
Returns the port number the parser uses for user connections.
If no argument is given, the port for this_player() is returned. If this_player() doesn’t exist or isn’t interactive, the first port number open for connections is returned.
If a user object is given, the port used for its connection is returned. If a positive number is given, the :arg:`num`th port number the parser uses for connections is returned (given that there are that many ports). If -1 is given, the number of ports open for connections is returned.
