拆分问题：“NoneType”对象不可调用
我一直面临着分割/切片字符串的一个小问题：
import requests
from bs4 import BeautifulSoup
url = 'http://www.example.com'
r = requests.get(url)
soup = BeautifulSoup(r.text, 'html.parser')
titles = soup.find_all('span', attrs='secondaryInfo')
for title in titles:
print(title)
输出是这样的：
<span class="secondaryInfo">(1994)</span>
<span class="secondaryInfo">(1972)</span>
<span class="secondaryInfo">(1974)</span>
<span class="secondaryInfo">(2008)</span>
<span class="secondaryInfo">(1957)</span>
我想分割并获得几年，我尝试的每次分割/切片，我都会收到此错误： 我尝试了一切，例如：
year=title.split(">")
or
year = link.split('>')[1]
类型错误：“NoneType”对象不可调用
我做错了什么？我怎样才能得到“年”前。 (1974)
I have been facing a small problem with splitting/slicing string :
import requests
from bs4 import BeautifulSoup
url = 'http://www.example.com'
r = requests.get(url)
soup = BeautifulSoup(r.text, 'html.parser')
titles = soup.find_all('span', attrs='secondaryInfo')
for title in titles:
print(title)
the output is like this :
<span class="secondaryInfo">(1994)</span>
<span class="secondaryInfo">(1972)</span>
<span class="secondaryInfo">(1974)</span>
<span class="secondaryInfo">(2008)</span>
<span class="secondaryInfo">(1957)</span>
I want to split and get years , every split/slice I try , I get this error :
I tried everything for example :
year=title.split(">")
or
year = link.split('>')[1]
TypeError: 'NoneType' object is not callable
what am I doing wrong ? how can I get "Years" ex. (1974)

在此代码中，titles 变量是使用 find_all() 与您的过滤器匹配的所有标签和字符串的列表。您可以在
titles上运行 for 循环，并在每个元素上使用getText()来查找给定标签的文本如果您希望它们存储在列表中，您可以这段代码
