Adding usernames to the path of the url
===

I am building an application using webapp2 in Google App Engine. How do I pass the username into the url so that when the profile button is clicked, it takes the user to "/profile/username" where "username" is specific to the user?

My current handlers:

    app = webapp2.WSGIApplication([('/', MainPage),
                                   ('/signup', Register),
                                   ('/login', Login),
                                   ('/logout', Logout),
                                   ('/profile', Profile)
                                   ],
                                  debug=True)

the Profile class:

    class Profile(BlogHandler):
        def get(self):
            email = self.request.get('email')
            product = self.request.get('product')
            product_list = db.GqlQuery("SELECT * FROM Post ORDER BY created DESC LIMIT 10")
            self.render('profile.html', email = email, product = product, product_list = product_list)

I am trying to send each user to a Profile page that contains information in my database specific to them. Thanks
