我是非常新的编码，并试图得到一个基本的网页抓取代码的工作。代码的工作刚刚好，问题是，我不能得到CSV文件有任何信息。任何帮助将不胜感激。

from bs4 import BeautifulSoup

import requests

import csv

page_to_scrape = requests.get("https://www.scrapethissite.com/pages/")
soup = BeautifulSoup(page_to_scrape.text, "html.parser")
descriptions = soup.findAll("p", attrs=("class" == "lead session-desc"))
titles = soup.findAll("h3", attrs=("class" == "page-title"))

with open("scrapeinformation.csv", "w", newline="") as f:
    thewriter = csv.writer(f)

    for title, desc in zip(titles, descriptions):
        print(title.text + " - " + desc.text)
        thewriter.writerow([title.text, desc.text])
f.close()
