Sample output:
---------------

.. code-block::

    (Cmd) greet
    Hi, m0rin09ma3
    (Cmd) stock GOOG
    910.68

Explanation
------------

In the Application class, there are 2 methods (do_greet() for greeting, do_stock() for getting quotes from specified url)

.. code-block:: python

    def do_greet(self, line):
        print "Hi, %s" % os.getlogin()

    def do_stock(self, line):
        quote = {'s': line, 'f': 'l1'}
        target_url = 'http://download.finance.yahoo.com/d/quotes.csv'
        r = requests.get(target_url, params=quote)
        #print r.url
        print r.text
