Introduction

Welcome to Google App Engine! Creating an App Engine application is easy, and only takes a few minutes. And it's free to start: upload your app and share it with users right away, at no charge and with no commitment required.

Google App Engine applications can be written in the Python 2.7, Java, Go or PHP programming languages. This tutorial covers Python 2.7. If you would prefer to use Java, Go or PHP to build your applications, see the Java, Go or PHP guides.

In this tutorial, you will learn how to:

• build an App Engine application using Python
• use the webapp2 web application framework
• use the App Engine datastore with the Python modeling API
• integrate an App Engine application with Google Accounts for user authentication
• use Jinja2 templates with your app
• upload your app to App Engine

By the end of the tutorial, you will have implemented a working application, a simple guest book that lets users post messages to a public message board.

Get set up

Before we continue, you will need to download the App Engine Python SDK, which includes a web server application that simulates the App Engine environment, and tools to deploy your application to the App Engine production environment. Follow the directions for your operating system, then come back here so we can get going!
