I wrote the below code

    def required_label_tag(self, contents=None, attrs=None):
        'Required    label    tag'
        contents = (contents or escape(self.label))
        if self.field.required:
            if (not self.label.endswith('    *')):
                self.label += '    *'
                contents += '    *'
            attrs = {'class': 'required'}
        return original_function(self, contents, attrs)
    return required_label_tag

What's a good function header?
