It's not quite clear what you want to do.
If you want to create instances of class with a parametric name you can do
def createClass( name ):
answer = Dummy()
answer.__class__.__name__ = name
if you want a list of instances you simply can get it with code like this:
map( createClass, [ "foo", "bar", "and", "the", "like" ] )
