AttributeError: 'NoneType' object has no attribute 'find_all' when scraping wiki

from bs4 import BeautifulSoup
import requests

url = 'https://en.wikipedia.org/wiki/Berlin_Wall/'

cream = requests.get(url).content
soup= BeautifulSoup(cream, 'lxml')

for tr in table_rows:
print(td.text)

我正在使用 python3。我试图从维基百科页面中删除信息框,但不断收到 AttributeError: 'NoneType' object has no attribute 'find_all'。任何人都知道这个问题是什么?

您的脚本中有几个简单的错误:

  1. 从 url 字符串中删除最后一个正斜杠 (/)。

url = 'https://en.wikipedia.org/wiki/Berlin_Wall'

  1. td 在您的循环中不存在,因此将其更改为 tr:
print(tr.text)
