dynamism

I've been away from Python for awhile and I'm wondering whether Python got
less "dynamic" while I was away.

I thought you could just extend an object's attributes at run-time like this:

>>> p = object()
>>> p.x = 1
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'object' object has no attribute 'x'

I thought that you could access dictionary values with object syntax:

>>> x = { 'a': 1, 'b':2 }
>>> x
{'a': 1, 'b': 2}
>>> x.a
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'dict' object has no attribute 'a'

Maybe you could never do this as shown but I'm sure there were ways of getting
this effect. Anyone care to remind me?

Cheers, Steve.
