AttributeError: 'tuple' object has no attribute 'content'是什么意思？原部分代码如下

def movies_from_url(urls):
all_movie = []
for u in urls:
# r is a return datum,r is the object of response
r = requests.get( u ),
# page is bytes tape
page = r.content
# root is a structure(texture) of tree
root = html.fromstring( page )
# return a list
moveie_divs = root.xpath( '//div[@class="item"]' )
movies = [movie_from_div( div ) for div in moveie_divs]
all_movie.extend( movies )
return all_movie

all_movie

div

return

@holajamc 我爬豆瓣 250 电影，相关图片内容都下载完了，然后报出这样的错误：Traceback (most recent call last):
File "/Users/zzz/Documents/Untitled.py", line 96, in <module>
main()
File "/Users/zzz/Documents/Untitled.py", line 92, in main
download_covers( movies )
File "/Users/zzz/Documents/Untitled.py", line 81, in download_covers
r = requests.get( imge_url )
NameError: name 'imge_url' is not defined，相关代码是：
def download_covers(movies):
for m in movies:
imag_url = m.cover_url
r = requests.get( imge_url )
path = 'covers/' + m.name.split( '/' )[0] + '.jpg'
with open( path, 'wb' ) as f:
f.write( r.content )

def main():
urls = urls_from_douban()
movies = movies_from_url( urls )

movie_log( movies )
download_covers( movies )

if __name__ == '__main__':
main()

感谢！
