Question

from bs4 import BeautifulSoup
import urllib.request
url = "http://www.python.tc/python-nedir"
url_oku = urllib.request.urlopen(url)
soup = BeautifulSoup(url_oku, 'html.parser')
icerik = soup.find_all('div',attrs={'class':'single-post-content'})
print(icerik[0].text)

Traceback (most recent call last):
  File "C:\Users\hira\AppData\Local\Programs\Python\Python35\d.py", line 11, in <module>
    print(icerik[0].text)
IndexError: list index out of range

Answer 1

查看源代码，页面不包含类<div>的{{1}}。要获取帖子内容，请尝试获取single-post-content标签：

<article>

这将打印：

from bs4 import BeautifulSoup
import urllib.request
url = "http://www.python.tc/python-nedir"
url_oku = urllib.request.urlopen(url)
soup = BeautifulSoup(url_oku, 'html.parser')

icerik = soup.find('article',attrs={'class':'single-post'})
print(icerik.text)

print（icerik [0] .text）IndexError：列表索引超出范围错误
