Problem
-------
Write a script to define 2 commands 'stock' and 'greet' for the shell cmd2 imported from Cmd module. 
1.Stock <nasdaqsymb> will return the current sharevalue of the symbol entered.
2.Greet, will return "Hi!, <username>"

Solution
--------
From 'Greet' command I have used getuser()
From 'Stock <nasdaqsymb> I have used requests.get()

Code
----
  ::
    from cmd2 import Cmd
    from getpass import getuser
    import sys
    import requests

__version__ = '0.1'

class Application(Cmd):
    """
    The main Application class
    """

    def __init__(self):
        Cmd.__init__(self)
    def do_hello(self, line):
        print "Hello:", line
    def do_sayit(self,line):
        print "Python Rocks!"
    def do_stock(self,line):
        """
        using requests.get() to get the url and then printing the value of the stock inputted
        """
        r=requests.get('http://download.finance.yahoo.com/d/quote.csv?s='+line+'&f=l1')
        data=r.text
        value=float(data)
        print value
    def do_greet(self,line):
        """
        getuser() used to get the user that is logged in 
        """
        print "Hi! %s" %(getuser())

if __name__ == '__main__':
    app = Application()
    app.cmdloop()
