[英]How can I get data from a website using BeautifulSoup and requests?
[英]Why can't I get scarped data from a website with BeautifulSoup? I'm getting timeout error
我試圖從以下網站獲取數據,但出現以下錯誤。 PFB的代碼相同。
from urllib2 import urlopen
import bs4 as bs
response = urlopen('http://www.mec.ac.in/mec/stats2018.php')
html = response.read()
soup = bs.BeautifulSoup(response,'lxml')
print soup.title
PFB錯誤:
