Python Error: TypeError: 'NoneType' object is not callable

Question

下面是我的代码和我遇到的错误

import requests
import BeautifulSoup
from BeautifulSoup import BeautifulSoup

url = "http://www.indeed.com/jobs?  q=hardware+engineer&l=San+Francisco%2C+CA"

r = requests.get(url)
soup = BeautifulSoup(r.content)

job_titles = soup.find_all("a", {"class", "jobtitle"})

print job_titles

我得到的错误：

Traceback (most recent call last):
  File "webscraping.py", line 13, in <module>
    job_titles = soup.find_all("a", {"class", "jobtitle"})
TypeError: 'NoneType' object is not callable

Answer 1

表示soup.find_all是None。确保它不是 none。此外，我在您的代码中注意到的另一件可疑的事情是 imports

import BeautifulSoup
from BeautifulSoup import BeautifulSoup

确保导入其中任何一个并相应地修改

soup = BeautifulSoup(r.content)

Answer 2

您使用的 BeautifulSoup 3 似乎没有 find_all，只有 findAll.

如果您要使用 BeautifulSoup，请使用 findAll 3.

或使用BeautifulSoup 4 to use find_all:

from bs4 import BeautifulSoup

Answer 3

下面对我有用 - jobtitle 是 h2 的 class 名称而不是 a。我和 bs4 '4.4.0'

import requests
from bs4 import BeautifulSoup

url = "http://www.indeed.com/jobs?  q=hardware+engineer&l=San+Francisco%2C+CA"

r = requests.get(url)
soup = BeautifulSoup(r.content)

job_titles = soup.find_all("h2", {"class", "jobtitle"})

for job in job_titles:
    print job.text.strip()
