class like this. Everything seems to work as I would expect.
class foo(object):
def __init__(self, x):
self.letter = dict(a=1,b=2,c=3)
self.A=self.letter['a']
self.x=self.letter[x]
afoo = foo('b')
afoo.x
2
afoo.A
1
afoo.letter['a']
1
afoo.letter.items()
[('a', 1), ('c', 3), ('b', 2)]
Do you expect afoo.letter[x] to always be afoo.x? Because they aren't:
afoo.A = 9
afoo.letter['a']
1

It's possible, and not too tough, but... why do you need it done that way?

Not sure I do, basicly I have a long list of values that could be calculated from data. Some may take some time depending on the amount of data. I don't what to calculate them all if not needed but I don't what the user to need to know which are and which are not. But maybe @property is what I need to be looking at, see my other post on the list.
