Python on Symbian is a great way to start your adventure in mobile programming!

Python applications ("apps") look like native C++ apps, can access the same important platform services, and can be distributed through the same channels.

The main difference between Python apps and native C++ apps is that, because of Python's simple human readable syntax, you can write quite remarkable apps after only a few hours of study. Although some computationally intensive applications cannot be written in Python it is, for almost every other purpose, a fun, fast and completely free alternative to native C++ development.

Some example Python apps include:

Here are few screenshots of Python applications,

Who is this book for and what does it contain?

If you want to develop powerful mobile apps with the minimum effort and learning curve, this is the book for you!

It's intended for readers of all levels of experience, from beginners to advanced users of Python on Symbian. We don't assume any knowledge of Python and we cover (almost) everything from basic Python concepts, such as variables, functions and classes, to advanced concepts like platform services and advanced network programming.

We've divided the book into a series of self-contained chapters, each of which discusses a specific and important feature of Python on Symbian:

  • The first couple of chapters of the book introduce you to generic Python and to Python on Symbian. They cover the language, coding conventions, basic programming elements and how to get started.
  • The following chapters explore the user interface and show you how to write applications using telephony, messaging, graphics and multimedia.
  • Later in the book we look at advanced features: network programing, location-based services and platform services.
  • Two chapters briefly describe extending Python on Symbian and debugging techniques.
  • The book also describes how to package and sign your apps so that they can be published to app stores.

Throughout the book you'll find illustrations, screenshots and example code. It's a book to boost your knowledge of mobile phone programming and make it fun!

If you're already familiar with the popular book about using Python on Symbian published in 2007 (Mobile Python: Rapid prototyping of applications on the mobile platform, by Jurgen Scheible and Ville Tuulos, John Wiley & Sons), you'll find this book to be its natural successor. This book has a slightly different focus, with its emphasis on developing fully-fledged Python applications, so even if you're already a Python expert from reading Jurgen's book we hope that you will still get something out of this one. Python for Symbian has been updated since that book was released and has new ways of deploying and installing apps.

Python version used in the book

This book is based on Python on Symbian v2.0.0, the most recent version available at time of writing, which is in turn based on the Python 2.5.4 release.

Even though the book targets Python on Symbian v2.0.0, much of the information is applicable to earlier versions and most is likely to remain relevant in future versions. Since we are publishing the book on wiki, we will update sections as they become out of date (and encourage readers to do likewise). If you are reading this book in print version, you may wish to check the main wiki page (http://www.developer.nokia.com/Community/Wiki/index.php/Category:Python) to see if there have been major updates to the text since your book was printed.

Python on Symbian is hosted by the Maemo garage. See https://garage.maemo.org/frs/?group_id=854 for the package landing page.
