　　实时抓取网页数据(我正在尝试从这个网页中获取实时商品价值它有一个iframe)

　　我正在尝试从此网页获取实时产品价值。它有一个 iframe 地址::8000/

　　这是我用 BeautifulSoup 尝试过的：

　　from bs4 import BeautifulSoup

#import time

import urllib

data = []

url=urllib.urlopen("http://213.136.84.136:8000/")

html=url.read()

url.close()

soup = BeautifulSoup(html,"html.parser")

span=soup.find('table', attrs={'class':'table2'})

table_body = span.find('tbody')

rows = table_body.find_all('tr')

for row in rows:

cols = row.find_all('td')

cols = [ele.text.strip() for ele in cols]

data.append([ele for ele in cols if ele]) # Get rid of empty values

print([data])

　　这是我得到的输出：

　　[[[], [u'INTERNATIONAL MARKET'], [u'SPOT Gold'], [u'SPOT Silver'], [u'CrudeOil'], [u'Copper'], [u'NaturalGas'], [u'Dow Jones'], [u'Bank Nifty'], [u'INDIAN MARKET'], [u'MCXGold'], [u'MCXSilver'], [u'MCXCrudeOil'], [u'MCXCopper'], [u'MCXLead'], [u'MCXNickel'], [u'MCXZinc'], [u'MCXNaturalGas'], [u'MCXAluminium'], [u'MCXMenthaOil'], [u'USDINR'], [], [u"Disclaimer: We can't assure any guarantee about the accuaracy of the data."]]]

　　它不返回任何引号。你知道吗？
