“NoneType”對象沒有 Beautifulsoup 的“find_all”屬性

Question

我已經嘗試了我找到的這段代碼，但是它給了我 AttributeError 的錯誤消息：'NoneType' object has no attribute 'find_all' 我不熟悉 Beautifulsoup 並且不知道如何解決這個問題。 試圖找到一個解決方案，我忽略了 tabpane 部分，但無法弄清楚。 你有什么建議嗎？

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')

抓取頁面中的所有表格：

tables = pd.read_html("https://www.marketwatch.com/tools/earnings-calendar")

只看第一個：

print(tables[0].head())

如果您確定所有表都具有相同的列，則可以將它們連接為只有一個數據框：

df = pd.concat(pd.read_html("https://www.marketwatch.com/tools/earnings-calendar"))
