I'm quite new to programming in Python.
I want to make an application which will fetch stock prices from google finance. One example is CSCO (Cisco Sytems). I would then use that data to warn the user when the stock reaches a certain value. It also needs to refresh every 30 seconds.
The problem is I dont have a clue how to fetch the data!
Anyone have any ideas?
Stocker is a Python class-based tool used for stock prediction and analysis. (for complete code refer GitHub) Stocker is designed to be very easy to handle. Even the beginners in python find it that way.

Program:
import urllib
import re
def get_quote(symbol):
base_url = 'http://finance.google.com/finance?q='
content = urllib.urlopen(base_url + symbol).read()
m = re.search('id="ref_694653_l".*?>(.*?)<', content)
if m:
quote = m.group(1)
else:
quote = 'no quote available for: ' + symbol
return quote
Sample Usage:
import stockquote
print stockquote.get_quote('goog')
Update: Changed the regular expression to match Google Finance's latest format (as of 23-Feb-2011). This demonstrates the main issue when relying upon screen scraping.
