Python 试着用硒和BS来筛选刮屑。得到一个奇怪的错误，它不会'；似乎一点也不合乎逻辑

我正试图从这个链接中获取一些数据

{%2215%22:%22115%22}&pageSize=250&page=

下面是我正在测试的代码

from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait
from bs4 import BeautifulSoup
import time
from time import sleep

browser = webdriver.Chrome("C:/Utility/chromedriver.exe")
wait = WebDriverWait(browser, 10)

url = 'https://www.congress.gov/members?q={%22congress%22:%22115%22}&pageSize=250&page='
browser.get(url)

time.sleep(10) # wait page open complete

html = browser.page_source
soup = BeautifulSoup(html, "html.parser")

data = soup.findAll('div',attrs={'class':'expanded'})
for div in data:
    links = div.findAll('a')
    for a in links:
        print(a['href'])

我不断地发现这个错误：

  File "C:\Users\Excel\Anaconda3\lib\site-packages\selenium\webdriver\common\service.py", line 6, in <module>
    forest.fit(X_train, y_train)

NameError: name 'X_train' is not defined

我正在使用Spyder 3.6。谢谢。

您似乎试图在代码的某个地方使用

X\u train

变量而不声明。我已经测试了您的代码示例，只做了一次调整，它就如预期的那样工作了：在下面的行中将

div

替换为

li

：data=soup.findAll（'div'，attrs={class'：'expanded'}）我刚刚做了同样的更改。我仍然得到同样的错误。看起来好像有什么东西被塞进了记忆，但我不知道它是什么。我刚刚创建了一个新的Sypder实例并启动了一个新节点…我仍然收到这个错误，它似乎与任何事情都完全无关…好的，我卸载了Selenium，然后重新安装了Selenium。现在一切正常。
