I wrote the below code

    def warn_on_use():
        warnings.warn((u'The    "%s"    signal    argument    for    "%s"    has    been    deprecated    and    will    be    removed    in    a    future    version.
   use    "%s"    instead.' % (old_name, signal_name, new_name)), DeprecationWarning)
        return value
    return SimpleLazyObject(warn_on_use)

What's a good function header?
