Your snippet above will set the attribute "key" to kwargs[k] (it will 
overwrite the values for the previous keys so you won't get anywhere).

You need to use setattr to do this since the names of the attributes are 
available as strings. Here's an example.

 >>> class Foo(object):
...   def __init__(self,**d):
...    for i in d:
...     setattr(self,i,d[i])
...
 >>>
 >>>
 >>> x= Foo(name="Papa")
 >>> x.name
'Papa'
 >>>
