Scraping Google Finance (BeautifulSoup)
I'm trying to scrape Google Finance, and get the "Related Stocks" table, which has id "cc-table" and class "gf-table" based on the webpage inspector in Chrome. (Sample Link: https://www.google.com/finance?q=tsla)
But when I run .find("table") or .findAll("table"), this table does not come up. I can find JSON-looking objects with the table's contents in the HTML content in Python, but do not know how to get it. Any ideas?
The page is rendered with JavaScript. There are several ways to render and scrape it.
I can scrape it with Selenium. First install Selenium:
sudo pip3 install selenium
Then get a driver https://sites.google.com/a/chromium.org/chromedriver/downloads
import bs4 as bs
from selenium import webdriver
browser = webdriver.Chrome()
url = ("https://www.google.com/finance?q=tsla")
browser.get(url)
html_source = browser.page_source
browser.quit()
soup = bs.BeautifulSoup(html_source, "lxml")
for el in soup.find_all("table", {"id": "cc-table"}):
print(el.get_text())
Alternatively PyQt5
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.QtWebKit import *
from PyQt5.QtWebKitWidgets import QWebPage
from PyQt5.QtWidgets import QApplication
import bs4 as bs
import sys
class Render(QWebPage):
def __init__(self, url):
self.app = QApplication(sys.argv)
QWebPage.__init__(self)
self.loadFinished.connect(self._loadFinished)
self.mainFrame().load(QUrl(url))
self.app.exec_()
def _loadFinished(self, result):
self.frame = self.mainFrame()
self.app.quit()
url = "https://www.google.com/finance?q=tsla"
r = Render(url)
result = r.frame.toHtml()
soup = bs.BeautifulSoup(result,'lxml')
for el in soup.find_all("table", {"id": "cc-table"}):
print(el.get_text())
Alternatively Dryscrape
import bs4 as bs
import dryscrape
url = "https://www.google.com/finance?q=tsla"
session = dryscrape.Session()
session.visit(url)
dsire_get = session.body()
soup = bs.BeautifulSoup(dsire_get,'lxml')
for el in soup.find_all("table", {"id": "cc-table"}):
print(el.get_text())
all output:

EDIT
QtWebKit got deprecated upstream in Qt 5.5 and removed in 5.6.
You can switch to PyQt5.QtWebEngineWidgets
Most website owners don't like scrapers because they take data the company values, use up a whole bunch of their server time and bandwidth, and give nothing in return. Big companies like Google may have entire teams employing a whole host of methods to detect and block bots trying to scrape their data.
There are several ways around this:
- Scrape from another less secured website.
- See if Google or another company has an API for public use.
- Use a more advanced scraper like Selenium (and probably still be blocked by google).
