Python BeautifulSoup在写入csv时解决网站上丢失的数据

from bs4 import BeautifulSoup
import csv

# 假设网页内容存储在变量html中
soup = BeautifulSoup(html, 'html.parser')

# 假设需要提取的数据位于一个特定的HTML标签中，例如<div class="data">...</div>
data_div = soup.find('div', class_='data')

if data_div is not None:
    # 提取数据
    data = data_div.text
else:
    # 处理数据丢失的情况
    data = "数据丢失"

# 假设要写入的CSV文件名为data.csv
with open('data.csv', 'w', newline='') as csvfile:
    writer = csv.writer(csvfile)
    writer.writerow(['数据'])
    writer.writerow([data])
