I need help to use TORNADO in PYTHON.

I have written a small code, but suppose, after making this a simple page, I want to count up every single time someone requests to visit the page. Every time the page is refreshed will give the correct number, it shouldn't need to be dynamically. What should I add? Kindly write comment to explain also. And If I have to make new file to do that then please say in details. I am new in this area.

I have copied the program I wrote-

from tornado import httpserver from tornado import gen from tornado.ioloop import IOLoop import tornado.web

class MainHandler(tornado.web.RequestHandler): def get(self): self.write("Hello World")

class HtmlHandler(tornado.web.RequestHandler): def initialize(self, ref_object = None): self.ref_object = ref_object def get(self): self.render('firstPage.html')

class App(tornado.web.Application):

def __init__(self): handlers = [ (r"/?", MainHandler), (r"/html/?", HtmlHandler) ] tornado.web.Application.__init__(self, handlers)

def main(): a = App() a.listen(8888) IOLoop.instance().start()

if __name__ == '__main__': main()
