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()
