雅虎财经的 BeautifulSoup 和资产负债表问题

Question

我正在尝试使用 python 和 Beautiful Soup 从雅虎财经下载损益表和资产负债表。我设法下载了两个表，但无法下载嵌套信息， 例如：在总资产中还有其他两个信息，如流动资产和非流动资产，但我的程序只下载了总资产，而不下载其他两个子语音。

def stock_scraper(ticker):

    url_ce = ('https://finance.yahoo.com/quote/'+ticker+'/financials?p='+ticker)
    r_ce = requests.get(url_ce)

    web_content_ce = BeautifulSoup(r_ce.text, 'lxml')

    url_sp = ('https://finance.yahoo.com/quote/'+ticker+'/balance-sheet?p='+ticker)
    r_sp = requests.get(url_sp)

    web_content_ce = BeautifulSoup(r_ce.text, 'lxml')
    web_content_sp = BeautifulSoup(r_sp.text, 'lxml')

    return web_content_ce, web_content_sp, ticker


def ce_preparator(web_content, ticker):

    web_content = web_content.find('div', class_='D(tbrg)')
    web_content = web_content.get_text(separator='\n')

    file = open("ce_"+ticker+".txt", "w")
    file.write(web_content)
    file.close()


def sp_preparator(web_content, ticker):

    web_content = web_content.find('div', class_='D(tbrg)')
    web_content = web_content.get_text(separator='\n')

    file = open("sp_"+ticker+".txt", "w")
    file.write(web_content)
    file.close()

PS：CE 表示损益表，SP 表示资产负债表
