No.

    ports = [('5631', 'udp'),
             ('5632': 'tcp'),
             ('3389': 'tcp'),
             ('5900': 'tcp')]

    for port,protocol in ports:
        print port, protocol  # ...

You'd append with

   ports.append(('2345', 'tcp'))

note the double set of parentheses since you're appending a tuple.
