How to Use this Book
With a simple text editor and a Nokia smartphone, you can instantly code
and test working applications found in this book. You will learn things
by running small yet fully working programs on the actual phone to see
what they do and then study and modify them on your computer. By
experiencing the hands-on coding style and ready-to-use programs, you
can soon feel success that keeps you inspired throughout the book.
This book includes over 100 example programs that demonstrate different
aspects of the mobile platform. The code for all example programs
can be downloaded for free from www.mobilepythonbook.com. Some of
the programs are small scripts that show you how to automate tasks, such
as sending SMS messages; some are full-scale applications with graphical
user interfaces. The examples are designed in such a way that they often
build on each other, which makes learning easier through repetition.
Most of the examples demonstrate a specific functionality, so they are
short and easy to understand – the median length of examples is just 17
lines of code! However, many of the examples are not just for playing
around but are already usable solutions in their own right.
The examples in this book are designed to be combined, modified
and enhanced by your own ideas. Throughout the book, examples are
cross-referenced with each other, so the book can also be ‘dipped into’
and not necessarily read from cover to cover.
Besides many examples, Chapters 3 to 6 contain some Python language
lessons. These lessons, spanning at most a page, introduce you to
the basic concepts of the Python programming language. They provide
you necessary knowledge on the language, so you can follow examples
and extend them by yourself. Even though the lessons cover the basic
concepts in Python, they omit many of its interesting and useful features.
As the lessons deal with Python in general and not specifically about
Python on the mobile platform, you can easily find more information
about the topics in many books and Python tutorials on the web (see the
References section).
However, you will be surprised how far you get with 14 one-page
lessons on Python!
