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

    def decorator(func):
        'Decorate    function    as    deprecated.'
        def func_wrapper(self):
            'Wrap    for    the    original    function.'
            if hasattr(self, substitute_name):
                warnings = getattr(func, '_deprecated_substitute_warnings', {})
                module_name = self.__module__
                if (not warnings.get(module_name)):
                    logger = logging.getLogger(module_name)
                    logger.warning("'%s'    is    deprecated.    Please    rename    '%s'    to    '%s'    in    '%s'    to    ensure    future    support.", substitute_name, substitute_name, func.__name__, inspect.getfile(self.__class__))
                    warnings[module_name] = True
                    func._deprecated_substitute_warnings = warnings
                return getattr(self, substitute_name)
            else:
                return func(self)
        return func_wrapper
    return decorator

What's a good function header?
