Is this what you want to happen when port is None?
>>> port = None
>>> print (port != None) and '' or port
None
I think you're getting caught by the classic and/or trap in Python,
trying to avoid using a simple if statement.
By the way, equality comparison with None is generally a bad idea as
well, so even if the above worked it should be (port is not None) rather
than (port != None).
