я есть набор ссылок, таких как:

['http://www.nytimes.com/2016/12/31/us/politics/house-republicans-health-care-suit.html?partner=rss&amp;emc=rss" rel="standout"></atom:link>',
 'http://www.nytimes.com/2016/12/31/nyregion/bronx-murder-40th-precinct-police-residents.html</guid>',
 'http://www.nytimes.com/2016/12/30/movies/tyrus-wong-dies-bambi-disney.html?partner=rss&amp;emc=rss',
 'http://www.nytimes.com/2016/12/30/obituaries/among-deaths-in-2016-a-heavy-toll-in-pop-music.html</guid>',
 'http://www.nytimes.com/video/world/100000004830728/daybreak-around-the-world.html?partner=rss&amp;emc=rss']

Я пытаюсь перебрать их, чтобы удалить все, что идет послеhtml, Так что я:

cleanitems = []

for item in links:  
    cleanitems.append(re.sub(r'html(.*)', '', item))

Который возвращает:

['http://www.nytimes.com/2016/12/31/us/politics/house-republicans-health-care-suit.',
 'http://www.nytimes.com/2016/12/31/nyregion/bronx-murder-40th-precinct-police-residents.',
 'http://www.nytimes.com/2016/12/30/movies/tyrus-wong-dies-bambi-disney.',
 'http://www.nytimes.com/2016/12/30/obituaries/among-deaths-in-2016-a-heavy-toll-in-pop-music.',
 'http://www.nytimes.com/video/world/100000004830728/daybreak-around-the-world.]

Смущен тем, почему это включаетhtml в группе захвата. Спасибо за любую помощь.
