Property with parameter...

[Marc Jeurissen]

Why not just like this or does this create 'hidden traps'?


class A:
     def __init__(self):
         self.__name = {}

     def __setname(self, name):
         for tag in name:
             self.__name[tag] = name[tag]

     def __getname(self):
         return self.__name

     name = property(__getname, __setname)

     def show(self):
         print self.__name



a = A()
a.name['one'] = 1
a.name['two'] = 2
a.show()
-> {'two': 2, 'one': 1}

print a.name['two']
-> 2
