| The Development Environment |
| =========================== |
| You develop and upload Python applications for Google App Engine using the App |
| Engine Python software development kit (SDK). |
| |
| The Python SDK includes a web server application that simulates the App Engine |
| environment, including a local version of the datastore, Google Accounts, and |
| the ability to fetch URLs and send email directly from your computer using the |
| App Engine APIs. The Python SDK runs on any computer with Python 2.5, and |
| versions are available for Windows, Mac OS X and Linux. The Python SDK is |
| not compatible with Python 3. |
| |
| The Python SDK for Windows and Mac includes Google App Engine Launcher, an |
| application that runs on your computer and provides a graphical interface that |
| simplifies many common App Engine development tasks. |
| |
| If necessary, download and install Python 2.5 for your platform from |
| `the Python web site <http://www.python.org/>`_. Mac OS X 10.5 Leopard users |
| already have Python 2.5 installed. |
| |
| `Download the App Engine SDK <http://code.google.com/appengine/downloads.html>`_. |
| Follow the instructions on the download page to install the SDK on your |
| computer. |
| |
| For this tutorial, you will use two commands from the SDK: |
| |
| - `dev_appserver.py <http://code.google.com/appengine/docs/python/tools/devserver.html>`_, the development web server |
| - `appcfg.py <http://code.google.com/appengine/docs/python/tools/uploadinganapp.html>`_, for uploading your app to App Engine |
| |
| Windows and Mac users can run Google App Engine Launcher and simply click the |
| Run and Deploy buttons instead of using these commands. |
| |
| For Windows users: The Windows installer puts these commands in the command |
| path. After installation, you can run these commands from a command prompt. |
| |
| For Mac users: You can put these commands in the command path by selecting |
| "Make Symlinks..." from the "GoogleAppEngineLauncher" menu. |
| |
| If you are using the Zip archive version of the SDK, you will find these |
| commands in the ``google_appengine`` directory. |
| |

| ------- |
| The local development environment lets you develop and test complete App Engine |
| applications before showing them to the world. Let's write some code. |
