Python has a handy builtin called vars that will give the attributes to you as a dict:

>>> a = A()
>>> vars(a)
{'myinstatt2': 'two', 'myinstatt1': 'one'}

To get just the attribute values, use the appropriate dict method:

>>> vars(a).values()
['two', 'one']

In python 3, this will give you a slightly different thing to a list - but you can just use list(vars(a).values()) there.

Try to look into the __dict__ attribute. It will help you:

a = A().__dict__.values()
print a
>>> ['one', 'two']

Given that A is the class, shouldn't it be A().__dict__.values()? – happydave Nov 21 '12 at 04:22
