请问python里面的@什么意思？

[edwardhey]

比如

@orm.validates('title')
    def validate_title(self, key, title):
        """Assure that page titles are wikiwords and valid length"""
        if len(title) > 40:
            raise ValueError('Page title must be 40 characters or fewer')
        if not wikiwords.match(title):
            log.warning('%s: invalid title (%s)' % (self.__class__.__name__,
                                                    title))
            raise ValueError('Page title must be a wikiword (CamelCase)')
        return title
