我希望得到上述所有标记,使用
为在soup.select(#房源的细节列表里跨度):
打印spans_others.append(a.text)
,但它不工作。谁能告诉我是什么问题?我使用Python中美味的汤。
为在soup.select(#房源的细节列表里跨度):
有与这条线没问题,假设你试图让所有的跨度
的上市的细节列表标签下code> ID。参见:
为在soup.select(#房源的细节列表里跨度):
打印一

您的问题是,你正试图打印
的结果的追加
电话:
打印spans_others.append(a.text)
和 list.append
总是返回无
(发生变异的名单,它没有收益
任何东西)。
A = [] .append(4)一个是无
出[19]:真
因此,无论打印 spans_others
你完成追加到它之后,或打印(一)
,或等
<div id="listing-details">
<div id="listing-details-list">
<h3 class="listing-details-header">
<ul class="important-fields">

I want to get all the above tags, using
for a in soup.select("#listing-details-list li span"):
print spans_others.append(a.text)
but it doesn't work. Can anyone tell me what the problem is? I am using Beautiful Soup in Python.
for a in soup.select("#listing-details-list li span"):
There is no problem with this line, assuming you're trying to get all the span
tags under the listing-details-list
id. See:
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>
Your problem is that you are trying to print
the results of an append
call:
print spans_others.append(a.text)
and list.append
always returns None
(it mutates the list, it doesn't return
anything).
a = [].append(4)
a is None
Out[19]: True
So either print spans_others
after you're done appending to it, or print(a)
, or etc.
