我需要提取html代码的这些值：
2018-04-01
1,500,552
7,211
3,710
我曾经使用过find_all但我的问题是在这个HTML中我不知道如何找到元素
这是我的代码：
from bs4 import BeautifulSoup as Soup
import requests
print 'Fecha Inicio ej:2018-04-01'
start = raw_input()
print 'Fecha Fin ej:2018-04-01'
end = raw_input()
glob2 = []
urls = ['http://url.com/rtbpartners/report.php?partner=id&date_from={}&date_to={}&interval=daily'.format(start, end)]
for item in urls:
data = requests.get(item)
data = data.text
print data
soup = Soup(data, "html.parser")
print soup.find_all('tr')
HTML示例：
<!DOCTYPE html>

您永远不会在for循环之前检索任何元素，因此循环无需查找。我建议在for循环之前放置你的“find_all（）”然后执行它。然后添加更多for循环来遍历所有标记以找到要查找的特定标记。 包括一些if循环，如
if tag.name == "td":
(code here)
我还建议您查看lxml用于使用xpath在网页上查找特定项目。

这样的事情应该有效：
soup = bs4.BeautifulSoup(content, 'lxml')
for table_row in soup.find_all(name="tr"):
if table_row.parent.name == "tbody":
for content in table_row.find_all("td"):
print(content.getText().strip())
它在Python 3中使用了BeautifoulSoup4，但是你在使用Python2时没有任何困难。
结果：
2018-04-01
1,500,552
7,211
3,710
1.43
