我希望使用

获取以上所有标签

for a in soup.select("#listing-details-list li span"):
    print spans_others.append(a.text)

但它不起作用。谁能告诉我这是什么问题？我在Python中使用Beautiful Soup。

Answer 1

for a in soup.select("#listing-details-list li span"):

此行没有问题，假设您尝试获取span ID下的所有listing-details-list标记。参见：

for a in soup.select("#listing-details-list li span"):
    print a
<span> Property Reference: </span>
<span> Furnished: </span>
<span> Listed By: </span>
<span> Rent Is Paid: </span>
<span> Building: </span>
<span> Amenities: </span>
<span>Listed by:</span>

您的问题是，您正试图print append来电的结果：

print spans_others.append(a.text)

和list.append始终返回None（它会改变列表，它不会return任何内容。

a = [].append(4)

a is None
Out[19]: True

因此，在您完成追加后，请先打印spans_others，或print(a)等等。

如何在美丽的汤中获得类似的标签？
