CODE TO THE PROGRAM
----------------------
 the program is based on printing the current shrevalue of the nsdaq 

.. code:: python

   #!/usr/bin/env python

   import urllib2

   import sys

   def get_value(nasdaq): #to get the share value of nasdaq

    this function will get the share value of nasdaq

        url='http://download.finance.yahoo.com/d/quotes.csv?s=%s&f=l1' % (nasdaq) #this the url of the nasdaq syambol extracted from yahho.finance

        con=urllib2.urlopen(url) #to open the url
        
        val=con.read() #to read the current share value of nasdaq symbol from yahoo.finanace


        print "the current sharevalue is %s" % (val)

    if __name__ == '__main__': #it calls the function to get the current sharevalu

    if len(sys.argv) == 2: #condition to check whter the file name in the command line does not exceed two

  it will check for the number of arguments in command line with ./shareval.py

      get_value(sys.argv[1]) #passe the nasdaq to the main user
    
 else:

      print "Give only one NASDAQ symbol at a time after command line argument!"
    
 sys.exit(0)



The explanation o the code
---------------------------

Here we use import urllib2 to get the current share value of symbol NASDAQ by using a function get_val.Now we open the url lin and read it to get the current sharevalue and print it.
'_main_' is used to check weather in the command line input only one input symbol  is given or more than one.If it exceed two includin the  ./shareval.py then it will exit else it will print the current sharevalue of the symbol
