Dictionary-like object in Python that allows setting arbitrary attributes

Question

What I want to do in my code:

myobj = <SomeBuiltinClass>()
myobj.randomattr = 1
print myobj.randomattr
...

I can implement a custom SomeClass that implements __setattr__ __getattr__. But I wonder if there is already a built-in Python class or simple way to do this?

Answer 1

You can just use an empty class:

class A(object): pass

a = A()
a.randomattr = 1

Answer 2

I like using the Bunch idiom for this. There are list of variations and some discussion here.
