I wrote the below code

    def log_slot(obj, signal, *args):
        'Slot    connected    to    a    signal    to    log    it.'
        dbg = dbg_signal(signal, args)
        try:
            r = repr(obj)
        except RuntimeError:
            r = '<deleted>'
        log.signals.debug('Signal    in    {}:    {}'.format(r, dbg))
    def connect_log_slot(obj):
        'Helper    function    to    connect    all    signals    to    a    logging    slot.'
        metaobj = obj.metaObject()
        for i in range(metaobj.methodCount()):
            meta_method = metaobj.method(i)
            qtutils.ensure_valid(meta_method)
            if (meta_method.methodType() == QMetaMethod.Signal):
                name = bytes(meta_method.name()).decode('ascii')
                if (name != 'destroyed'):
                    signal = getattr(obj, name)
                    try:
                        signal.connect(functools.partial(log_slot, obj, signal))
                    except TypeError:
                        pass
    if inspect.isclass(obj):
        old_init = obj.__init__
        @functools.wraps(old_init)
        def new_init(self, *args, **kwargs):
            'Wrapper    for    __init__()    which    logs    signals.'
            ret = old_init(self, *args, **kwargs)
            connect_log_slot(self)
            return ret
        obj.__init__ = new_init
        return obj
    else:
        connect_log_slot(obj)

What's a good function header?

Here's a good function header?
