=============
userfinder v2
=============

The assignment was

1. To write a command *greet*, which will say Hi! to user. Solution: Imported *getpass* module. It did the rest

2. To write a command *stock [NASDAQ]*, which will show the current share price of given NASDAQ symbol. Solution: Imported *sharevalue* module, which was our previous assignment. So just used it. I am too lazy to write same code again. *Well we have to use the requests liabrary. So modified the code of sharevalue. Modified code is also given here.*

Code
----

.. code:: python
    :number-lines:

    from cmd2 import Cmd
    from getpass import getuser
    from sharevalue import share

    __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_greet(self, line):
            print "Hi! %s" %(getuser())

        def do_stock(self, line):
            share(line)

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


Code for sharevalue using requests liabrary
-------------------------------------------

.. code:: python
    :number-lines:

    #!/usr/bin/env python

    import requests
    import sys

    def share(nasdaq):

        """
        Here all work is being done.

        :arg nasdaq: NASDAQ symbol
        """

        #Making the link in 'link' string to fetch data
        link = 'http://download.finance.yahoo.com/d/quotes.csv?s='+nasdaq+'&f=l1'
        print 'Fetching recent share value of '+nasdaq

        share_value = requests.get(link)

        print '\n'+'Current share price of company '+nasdaq+': '+share_value.text
        share_value.close()


    if __name__ == '__main__':
    
        #Counting the NASDAQ Symbol (Arguments)
        count = len(sys.argv) - 1 
    
        #Checking if atleast one symbol available or not
        if count >= 1:
        
            #NASDAQ symbol available passing it to main() function 
            i=0
            while i < count:
                i+=1
                share(sys.argv[i])
