How can I iterate over an object and assign all it properties to a list

Question

From

a = []

class A(object):
    def __init__(self):
        self.myinstatt1 = 'one'
        self.myinstatt2 = 'two'

to

a =['one','two']

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()?
