Congratulations, you’ve in the end get your first Python web app deployed on the Google App Engine. Here is another point which you may find beneficial, Jinja 2 is a top-notch front stop templating library for Python which could do some cool stuff, which includes moving objects from Python to HTML, the use of for loops, if situations, and so on at once out of the box.
