python - BS4 在 Python 中未定位元素

Question

我对 Python 有点陌生，我一生都无法弄清楚为什么下面的代码没有提取我想要获取的元素。

当前返回:

for player in all_players:

    player_first, player_last = player.split()
    player_first = player_first.lower()
    player_last = player_last.lower()
    first_name_letters = player_first[:2]
    last_name_letters = player_last[:5]

    player_url_code = '/{}/{}{}01'.format(last_name_letters[0], last_name_letters, first_name_letters)
    player_url = 'https://www.basketball-reference.com/players' + player_url_code + '.html'
    print(player_url) #test
    req = urlopen(player_url)
    soup = bs.BeautifulSoup(req, 'lxml')
    wrapper = soup.find('div', id='all_advanced_pbp')
    table = wrapper.find('div', class_='table_outer_container')


    for td in table.find_all('td'):
        player_pbp_data.append(td.get_text())

当前返回:

--> for td in table.find_all('td'):
        player_pbp_data.append(td.get_text()) #if this works, would like to 

AttributeError: 'NoneType' object has no attribute 'find_all'

注意:迭代包装对象的子对象会返回:

< div class="table_outer_container" >作为树的一部分。

谢谢!

确保表包含您期望的数据。

例如https://www.basketball-reference.com/players/a/abdulka01.html似乎不包含带有 id='all_advanced_pbp'

的 div
