嗨，我是用下面的代码来报废克雷格利斯特的。你知道吗

import pandas as pd
import requests
%pylab inline

url_base = 'http://houston.craigslist.org/search/apa'
params = dict(bedrooms=2)
rsp = requests.get(url_base, params=params)

print(rsp.text[:500])
from bs4 import BeautifulSoup as bs4
html = bs4(rsp.text, 'html.parser')
print(html.prettify()[:1000])

到目前为止一切正常，输出为：-

<!DOCTYPE html>
<html class="no-js">
 <head>
 <title>
  houston apartments / housing rentals  - craigslist
  </title>
<meta content="houston apartments / housing rentals  - craigslist" 
 name="description">
   <meta content="IE=Edge" http-equiv="X-UA-Compatible"/>
   <link href="https://houston.craigslist.org/search/apa" rel="canonical">
   <link href="https://houston.craigslist.org/search/apa?
   format=rss&amp;min_bedrooms=2" rel="alternate" title="RSS feed for 
   craigslist | houston apartments / housing rentals  - craigslist " 
   type="application/rss+xml">
     <link href="https://houston.craigslist.org/search/apa?
 s=120&amp;min_bedrooms=2" rel="next">
      <meta content="width=device-width,initial-scale=1" name="viewport">
       <link href="//www.craigslist.org/styles/cl.css?
 v=a14d0c65f7978c2bbc0d780a3ea7b7be" media="all" rel="stylesheet" 
 type="text/css">
    <link href="//www.craigslist.org/styles/search.css?v=27e1d4246df60da5ffd1146d59a8107e" media="all" rel="stylesheet" type="

它清楚地表明列表不是空的，并且有一些项目我可以使用。这是使用以下代码：-你知道吗

apts = html.find_all('p', attrs={'class': 'row'})
print(len(apts))

上述打印输出（len（apts））为0。。 有人能帮忙改正这个密码吗。我确实相信craiglisthtml解析器有一些变化，但我不知道如何在这里实现它。你知道吗

谢谢

没有带有'row'类的<p>标记，而<p>具有'result-info'类。你知道吗

import requests

url_base = 'http://houston.craigslist.org/search/apa'
params = dict(bedrooms=2)
rsp = requests.get(url_base, params=params)

print(rsp.text[:500])
from bs4 import BeautifulSoup as bs4
html = bs4(rsp.text, 'html.parser')
print(html.prettify()[:1000])

apts = html.find_all('p', attrs={'class': 'result-info'})
print(len(apts))
