Question

I am looking for a way to create a basic python “object” which I can externally assign attributes to.
Currently I am doing it the following way:

I define an empty class with

class C(object):
    pass

and then I instantiate an object and assign attributes like this:

c = C()
c.attr = 2

Coming to my question

Is there a way to instantiate an empty class object, which I can then assign attributes like shown above without defining a class C?

Is there maybe an other better way to accomplish what I am after?

Answer 1

It looks like you are looking for a flexible container that has no methods and can take attributes with arbitrary names. That’s a dict.

d = dict()
d['myattr'] = 42

If you prefer the attribute syntax that you get with a class (c.myattr = 42), then use a class just as per the code in your question.
