Declaring variable w/o knowing the name

This may seem a weird question but the thing is that I have a class to which I want to assign a variable (so using self.vname = Whatever in __init__), but this variable name is passed as wkargs in the instantiation.

So the class looks like

class Object(object):
    def __init__(self, **kwargs):
        for key in kwargs.keys():
            self.what_do_i_type_here = kwargs[key]

Actually this is a class which I will extend then so I am not sure how to do this.

I want to create a generic class which in each extension case will have different variables defined.

How to do so, or how to carry out a better approach?

I'm going to assume that you want the variable name to be the key.

You can use the setattr() built-in function:

for key in kwargs:
    setattr(self,key,kwargs[key])

You could use setattr:

for key, value in kwargs.items()
    setattr(self, key, value)

but I don't see the point, since you won't have any idea of the keys you've set so you won't be able to use them anywhere.

Why not keep them in a dictionary?

self.data = kwargs

then you can iterate through self.data and its values whenever you like.
