App Engine: Qwik Start - Python

LAB 3

Overview

App Engine allows developers to focus on doing what they do best, writing code. The App Engine standard environment is based on container instances running on Google's infrastructure. Containers are preconfigured with one of several available runtimes (Java 7, Java 8, Python 2.7, Go and PHP). Each runtime also includes libraries that support App Engine Standard APIs. For many applications, the standard environment runtimes and libraries might be all you need.

Now that the application is on the system, change to its directory and run it as shown below

cd python-docs-samples/appengine/standard_python3/hello_world
dev_appserver.py app.yaml

Now that the app is up and running, view it on port 8080 as shown below.

Modify the application and make it return something else.

cd python-docs-samples/appengine/standard_python3/hello_world
