我正在尝试阅读这篇文章 table。但无法这样做。我正在使用 beautyfulsoup findall 首先查找 div。 table 存在于 div 中。我找不到 table。第二个问题是遍历行的最佳方式是什么。例如，我想要 csv 格式的输出，应该用双引号括起来像： "STANDALONE","Jun'16","Mar'16","Dec'15","Sep'15" "Net Sales","16,339.70","15,589.40","15,065.00","14,824.50" "Other Income","50.10","46.30","153.30","1,087.40" "PBDIT","6,612.30","5,930.60","5,543.30","5,416.80" "Net Profit","1,427.50","1,693.90","1,709.10","2,223.70"

我的代码：

从 urllib.request 导入 urlopen 从 bs4 导入 BeautifulSoup 导入重新

html = urlopen("http://www.moneycontrol.com/india/stockpricequote/computers-software/tataconsultancyservices/TCS")
bsObj = BeautifulSoup(html, "html.parser")
link = bsObj.findAll("div", id="findet_1")
table1 = link.find('table').find_all('tr')

我知道我们可以使用 get_text 获取值并使用 for 循环遍历行。但我找不到 table :(

Answer 1

唯一的区别是 find_all() returns 包含单个结果的 list，而 find() 只是 returns结果。

如果 find_all() 找不到任何东西，它 returns 一个空列表。如果 find() 找不到任何东西，它 returns None:

link = bsObj.findAll("div", id="findet_1")
if link:
    table1 = link[0].find('table').find_all('tr')

Answer 2

试试这个：

table_div = html.find('div' , {'id': 'findet_1', 'name': 'findet_1' })
table = table_div.find('table')

或这个

table_div = html.find('div' , {'id': 'findet_1', 'name': 'findet_1' })
table = table_div.find_all('tr')
