I've just found a great online tutorial (available as stand-alone for offline learning) over at Forum Nokia website that will teach you about Python, the open source programming language optimized for rapid application prototyping.
It is an object-oriented scripting language that is easy to learn and use and supported on many platforms.
This module gives students an idea of where and how the language can be used, and show how to write Python programs that run on the S60 platform. The module assumes some familiarity with object-oriented programming languages.
Python is a dynamic object-oriented programming language that can be used for many kinds of software development. It offers strong support for integration with other languages and tools, comes with extensive standard libraries, and can be learned in a few days.
Many Python programmers report substantial productivity gains and feel the language encourages the development of higher quality, more maintainable code.
PyS60 is the Nokia's port of the Python language to the S60 smartphone platform. In addition to the standard features of the Python language, PyS60 provides access to many of uniquely Smartphone functions, such as camera, contacts, calendar, audio recording and playing, TCP/IP and Bluetooth communications and simple telephony.
