Answer 1

您可以使用内置字符串^{}方法。在

your_list = ["http://www.ragalahari.com/index.aspx",
"http://www.ragalahari.com/index.aspx",
"http://www.ragalahari.com/news.aspx",
"http://imgcdn.raagalahari.com/feb2015/photosessions/shraddha-das-in-long-black-frock/shraddha-das-in-long-black-frock1t.jpg",
"http://imgcdn.raagalahari.com/feb2015/photosessions/shraddha-das-in-long-black-frock/shraddha-das-in-long-black-frock2t.jpg",
"http://imgcdn.raagalahari.com/feb2015/photosessions/shraddha-das-in-long-black-frock/shraddha-das-in-long-black-frock3t.jpg",
"http://www.ragalahari.com/images/facebookicon.png",
"http://www.ragalahari.com/images/searchicon.png"]

img_links = []
for a in your_list:
    if a.endswith('png') or a.endswith('jpg'):
        img_links.append(a)

print img_links

您可以使用list comprehension和^{}：

images = [x for x in href_links if x.endswith(('jpg', 'png'))]
