My Google App Engine application is a workout followup utility. You can enter your times or distances, and the results are shown in list. Graphs were added using the Google Chart API. The URL is http://workoutfollowup.appspot.com/ (note : you will have to login with your Google ID). One of the things added recently is the ability to download the results as a csv file. The following code snippet shows how to do this.

Python‘s creator, Guido Van Rossum, has been hinting at this for a while, and it’s finally here : Google App Engine. It’s a way to build and host web apps on the Google servers.

On to some code : import cgi import wsgiref.
