Since (I presume) you are a newcomer to Python, it's best to learn the
common style <URL:http://www.python.org/dev/peps/pep-0008/>. I will
assume the above is written as::

    object_names = ['object1', 'object2', 'object3', 'object4']
    for object_name in object_names:
        object_name = Class()

Well, it succeeds (runs successfully). But I get what you mean: it fails
to do what you expected.

This is almost certainly better done with a dictionary. Like so::

    object_names = ['object1', 'object2', 'object3', 'object4']
    objects = {}
    for object_name in object_names:
        objects[object_name] = Class()

There are shortcuts that can be used to create the dictionary without
the separate list of names. But for now the above should make sense
immediately and help you get to the meat of the problem.
