Bad idea. Use a dict; don't try to pretend that an object is a dict.
This isn't Javascript. Incidentally, inheriting from "dict" works,
and is quite useful.
class item(dict) :
...
p = item()
p['abc'] = 1
That wasn't in early versions of Python, which led to a style of abusing
objects as if they were dictionaries.
Also note that 1) spaces in attribute names can be troublesome, and
2) duplicating the name of a function or built-in attribute will
override it, usually leading to unwanted results.
