Saya mencoba membatalkan situs web untuk latihan, tetapi saya terus mendapatkan Kesalahan HTTP 403 (apakah menurutnya saya bot)?
Ini kode saya:
#import requests
import urllib.request
from bs4 import BeautifulSoup
#from urllib import urlopen
import re
webpage = urllib.request.urlopen('http://www.cmegroup.com/trading/products/#sortField=oi&sortAsc=false&venues=3&page=1&cleared=1&group=1').read
findrows = re.compile('<tr class="- banding(?:On|Off)>(.*?)</tr>')
findlink = re.compile('<a href =">(.*)</a>')
row_array = re.findall(findrows, webpage)
links = re.finall(findlink, webpate)
print(len(row_array))
iterator = []
Kesalahan yang saya dapatkan adalah:
