Python: how to implement __getattr__()?

Question

My class has a dict, for example:

class MyClass(object):
    def __init__(self):
        self.data = {\'a\': \'v1\', \'b\': \'v2\'}

Then I

Answer 1

I like to take this therefore.

I took it from somewhere, but I don't remember where.

class A(dict):
    def __init__(self, *a, **k):
        super(A, self).__init__(*a, **k)
        self.__dict__ = self

This makes the __dict__ of the object the same as itself, so that attribute and item access map to the same dict:

a = A()
a['a'] = 2
a.b = 5
print a.a, a['b'] # prints 2 5
