I wrote the below code

    def load_app_hooks(app_name=None):
        hooks = {}
        for app in ([app_name] if app_name else get_installed_apps(sort=True)):
            app = (u'frappe' if (app == u'webnotes') else app)
            try:
                app_hooks = get_module((app + u'.hooks'))
            except ImportError:
                if local.flags.in_install_app:
                    pass
                print(u'Could    not    find    app    "{0}"'.format(app_name))
                if (not request):
                    sys.exit(1)
                raise
            for key in dir(app_hooks):
                if (not key.startswith(u'_')):
                    append_hook(hooks, key, getattr(app_hooks, key))
        return hooks
    if app_name:
        hooks = _dict(load_app_hooks(app_name))
    else:
        hooks = _dict(cache().get_value(u'app_hooks', load_app_hooks))
    if hook:
        return (hooks.get(hook) or (default if (default is not None) else []))
    else:
        return hooks

What's a good function header?

Give me a Python code to find    app    "{0}"'?
