     Name_Number = xrange(int(raw_input("Choose number of Names (1-20)? ")))

     state = [None,None]

                'Rita':['Mary','Sue','Bob'],\
                'Sue':['Rita','Mary','Bob'],\
                'Mary':['Sue','Rita']}

     Name_List = []

     tmp = choice(('Bob','Rita','Sue','Mary')) #after Mary ' missing

     for x in Name_Number:
         print 'state',state
