【问题描述】：

我已经尝试过我找到的这段代码，但是它给了我 AttributeError 的错误消息：'NoneType' object has no attribute 'find_all' 我不熟悉 Beautifulsoup，也不知道如何解决这个问题。试图找到一个解决方案，我忽略了 tabpane 部分，但无法弄清楚。你有什么建议吗？

import datetime
import pandas as pd # pip install pandas
import requests # pip install requests
from bs4 import BeautifulSoup # pip install beautifulsoup4

headers = {
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:87.0) 
Gecko/20100101 Firefox/87.0',
}
url = 'https://www.marketwatch.com/tools/earningscalendar'
response = requests.get(url, headers=headers)
soup = BeautifulSoup(response.content, 'html.parser')

tabpane = soup.find('div', 'tabpane')
earning_tables = tabpane.find_all('div', {'id': True})

dfs = {}
current_datetime = datetime.datetime.now().strftime('%m-%d-%y %H_%M_%S')
xlsxwriter = pd.ExcelWriter('Earning Calendar 
({0}).xlsx'.format(current_datetime), index=False)

for earning_table in earning_tables:
    if not 'Sorry, this date currently does not have any earnings 
announcements scheduled' in earning_table.text:
        earning_date = earning_table['id'].replace('page', '')
        earning_date = earning_date[:3] + '_' + earning_date[3:]
        print(earning_date)
        dfs[earning_date] = pd.read_html(str(earning_table.table))[0]
        dfs[earning_date].to_excel(xlsxwriter, sheet_name=earning_date, 
index=False)

xlsxwriter.save()
print('earning tables Excel file exported')

【问题讨论】：

tabpane 是None 和它后面的所有代码都是无关紧要的。
