Here is a snippet of python code that I am trying to use for downloading 
financial data; but, I do not understand why it returns information from 
the second HTML page.

   import urllib2
   '''
    I am trying to read each row of the table at:
     http://finance.yahoo.com/q/cp?s=^GSPC
   '''
   ticker = []
   url = 
urllib2.urlopen("http://download.finance.yahoo.com/d/quotes.csv?s=@%5EGSPC&f=sl1d1t1c1ohgv&e=.csv&h=PAGE".replace('PAGE', 
str(0)))
   data = url.read()

Note, it does get all 50 rows of the first page; but, why does it also 
get the first row of the "next" HTML page?
