Solve the following python programming problem given the following code:
def __init__(self, app, modules = [], injector = None, request_scope_class = RequestScope, use_annotations = None) : 
    'Initializes Injector for the application.

        .. note::

            Needs to be called *after* all views, signal handlers, template globals
            and context processors are registered.

        :param app: Application to configure
        :param modules: Configuration for newly created :class:`injector.Injector`
        :param injector: Injector to initialize app with, if not provided
            a new instance will be created.
        :type app: :class:`flask.Flask`
        :type modules: Iterable of configuration modules
        :param use_annotations: Enables Python 3 annotation support, see Injector
                                documentation for details.
        :type use_annotations: bool
        :rtype: :class:`injector.Injector`
        ' 
    if (injector and (self is not None)) : 
        raise AssertionError ('You cannot set use_annotations and pass Injector instance at the same time') 
if (not injector) : 
        kwargs = { 
            
} 
        if (use_annotations is not None) : 
            kwargs ['use_annotations'] = use_annotations 
injector = Injector (** kwargs) 
for module in ([FlaskModule (app = app, request_scope_class = request_scope_class)] + list (modules)) : 
        injector.binder.install (module) 
for container in (app.view_functions, app.before_request_funcs, app.after_request_funcs, app.teardown_request_funcs, app.template_context_processors, app.jinja_env.globals) :
