Alert message on Google App Engine for Python
Question: I want to pop an alert message for error handling on an app that runs via
Google App Engine for Python.

I tried this already but non worked:

`from Tkinter import * msg = Message(text="Please, make sure you fill out the
boxes and agree with the terms") msg.config(bg='green', font=('times', 16))
msg.pack() mainloop()`

AND

    
    
    import win32api
    win32api.MessageBox(0, 'hello', 'title')
    

I am guessing the Google App Engine has its own way of handling this task but
I can't figure out how.

Thank you!


Answer: You can't do that. The GAE server suppose to run headless, so you can't
display a popup in your host machine. If you use windows to launch de dev
server, simply use the log buton from the GUI or launch your dev server from
the command line.

To generate a debug log from your application you can simply see this post.
[Google app engine logging in dev
consol](http://stackoverflow.com/questions/3128393/google-app-engine-logging-
in-dev-console)

In production your application have a full admin panel with a lot of
possibilities and a logging pannelto see all messages from your app.
