My app, Datastore, webapp2, and form-specific “responses” are all working 🙂 but I need the page to load without displaying previous visitor’s query results. I need query results only for current form-submitter, after they submit form. Is this a session or headers solution, or can I edit the GqlQuery to accomplish this? 

messages = db.GqlQuery("SELECT * "
                                "FROM Visitor " 
                                "ORDER BY date DESC LIMIT 1") #obviously shows previous form submit
        for message in messages:
            if message.name == "" or message.mood == "":
                self.response.out.write("<div class='textright'>Type name and select.</div>")
                self.response.out.write("</body></html>")
            elif message.mood == "bad" and message.name != "":
                self.response.out.write("<body><html>")
                self.response.out.write("<div class='textright'>Stay the course

^ ^ this last section is my “response” that needs to appear only after current visitor submits form.

    I would strongly recommend you to go through the Getting Started and especially the templates section, until you will understand how it works.

    But you if you just want to see your example in action try this (read more):

    class Process(webapp.RequestHandler):
  def post(self):
    name = self.request.get("name")
    mood = self.request.get("mood")

    if mood == "bad" and name != "": 
      self.response.out.write("<html><body>")
      self.response.out.write("<h1>Welcome to the Internet!</h1>")
      self.response.out.write("<p>My mood is %s and my name is %s</p>" % (mood, name))
      self.response.out.write("</body></html>")
    else:
      self.response.out.write("<html><body>")
      self.response.out.write("<h1>Welcome to the Internet anyway!</h1>")
      self.response.out.write("</body></html>")

    Also never use print in your GAE applications, use the logger instead for debugging and more.
