that means I can neither have a dictionary with 2 identical keys but 
different values...?


I would need e.g. this:
(a list of ports and protocols, to be treated later in a loop)



ports = {'5631': 'udp', '5632': 'tcp', '3389': 'tcp', '5900': 'tcp'}
#then:
for port,protocol in ports.iteritems():
________print port,protocol
________#do more stuff


What would be the appropriate pythonic way of doing this?
