我正在尝试提取下面网站中所有行业和时期的表格。然而，当我下载 html 时，网站中显示的数字在任何地方都找不到。如何检索表中的条目？
https://csimarket.com/Industry/industry_Efficiency.php?ind=102
下面的代码提取了 html。经检查，表中的数字没有出现在任何地方，所以我无法提取它们。那么问题是他们在哪里？如何访问和提取它们？
请注意，我对请求和漂亮的汤很陌生! 非常感谢!
import requests
my_target='https://csimarket.com/Industry/industry_Efficiency.php?ind=102'
r = requests.get(my_target)
data = r.text
最佳答案
您可以使用requests，但需要使用r.content而不是r.text:
import requests
my_target='https://csimarket.com/Industry/industry_Efficiency.php?ind=102'
r = requests.get(my_target)
data = r.content
您还可以使用BeautifulSoup module解析 html，如下所示:
import requests
#load beautifullsoup
from bs4 import BeautifulSoup
my_target='https://csimarket.com/Industry/industry_Efficiency.php?ind=102'
r = requests.get(my_target)
#get raw html
data = r.content
#soup the content
soup = BeautifulSoup(data, 'html.parser')
#find table element
table_element = soup.find('table',{"class":"osnovna_tablica_bez_gifa"})
#print text version of table element
print table_element.text
这给你:
