Here's a good function header given the following:
I wrote the below code

    def when_module_enabled():
        tags.Registry.add_tag_binding(OppiaTag.binding_name, OppiaTag)
        tags.EditorBlacklists.register(OppiaTag.binding_name, tags.EditorBlacklists.COURSE_SCOPE)
        if (EXPLORATION_COMPLETED_EVENT_NAME not in lessons.TAGS_THAT_TRIGGER_COMPONENT_COMPLETION):
            lessons.TAGS_THAT_TRIGGER_COMPONENT_COMPLETION.append(EXPLORATION_COMPLETED_EVENT_NAME)
        if (OPPIA_TAG_BINDING_NAME not in progress.TRACKABLE_COMPONENTS):
            progress.TRACKABLE_COMPONENTS.append(OPPIA_TAG_BINDING_NAME)
    def when_module_disabled():
        tags.Registry.remove_tag_binding(OppiaTag.binding_name)
        tags.EditorBlacklists.unregister(OppiaTag.binding_name, tags.EditorBlacklists.COURSE_SCOPE)
        if (EXPLORATION_COMPLETED_EVENT_NAME in lessons.TAGS_THAT_TRIGGER_COMPONENT_COMPLETION):
            lessons.TAGS_THAT_TRIGGER_COMPONENT_COMPLETION.remove(EXPLORATION_COMPLETED_EVENT_NAME)
        if (OPPIA_TAG_BINDING_NAME in progress.TRACKABLE_COMPONENTS):
            progress.TRACKABLE_COMPONENTS.remove(OPPIA_TAG_BINDING_NAME)
    global_routes = [(os.path.join(RESOURCES_PATH, '.*'), tags.ResourcesHandler)]
    global custom_module
    custom_module = custom_modules.Module('Oppia    tag', 'A    tag    for    rendering    Oppia    explorations    within    a    lesson    body.', global_routes, [], notify_module_enabled=when_module_enabled, notify_module_disabled=when_module_disabled)
    return custom_module

What's a good function header?
