calibre의 recipe 파일을 python 으로 만들어야 하는데 잘 안되네요.

import re
 
class AdvancedUserRecipe1310988830(BasicNewsRecipe):
    title          = u'NaverCast'
    no_stylesheets         = True
    remove_javascript     = True
    oldest_article = 1
    language = 'ko'
    max_articles_per_feed = 10
    description = u'Naver cast'
    cover_url              = 'http://static.naver.com/ncc/image/casthome_normal.gif'
    remove_tags_before = dict(name='div', attrs={'class':'article'})
    remove_tags_after = dict(name='div', attrs={'class':'tooltip_prev'})
    extra_css      = 'article {font: sans-serif; text-align: left;} \n .smarteditor_area {font: sans-serif; text-align: left;} \n .pop_content {font: sans-serif; text-align: left;}'
    feeds          = [(u'naver', u'feed://feed43.com/today_navercast.xml')]
 
    def print_version(self, url):
        return url.replace('contents.nhn','contentsPopup.nhn')+'&is_print=Y'
