Question

我正在尝试从此website获取每篇文章的所有部分屏幕截图。我成功找到了下面的元素。

<div id="post-4474417" class="post-box    " data-permalink="https://hypebeast.com/2019/1/ten-best-sneakers-paris-fashion-week-fall-winter-2019-runway-shows" data-title="The 10 Best Sneakers From Paris Fashion Week's FW19 Runways">

但是，当我尝试使用element.text重命名屏幕快照时，我只是从网站的最后一个元素中提取了相同的名称。但是，当我使用print(item)输出时，它给了我所有不同的标题。我在这里做什么错了？

print(item)的输出：

巴黎时装周FW19跑道上的十佳运动鞋

sacai在FW19巴黎时装秀期间首次亮相新款Nike运动鞋

sacai的Whimsical SS19系列包括耐克合作款

Answer 1

im = im.crop((left, top, right, bottom)).save(str(i)+"_"+item+".png")

这将返回您的最后一个值，因为当您在循环结束时迭代循环时，您将只会获得最后一个值。

由于列表元素element_item中已经具有列表值，因此可以在下一个for循环中使用该列表。

i = 1
for product in products:

 im = im.crop((left, top, right, bottom)).save(str(i)+"_"+ element_item[i-1] +".png")

 i=i+1
