Welcome to the forum! When it comes to Python on App Engine, you generally have 2 options, deploy to the App Engine standard environment or the flexible environment. The
Quick Start guide for the standard environment shows a
Hello, world example using the
webapp2 framework. The
flexible environment Quick Start guide shows a similar example however using the
Flask framework. I'd recommend reviewing those guides to get an idea of the steps involved in creating, configuring and deploying an App Engine application.
