The pages accessed via the CODING menu give details about the algorithms and Python code of the programs made available from the site.

Needing a new pastime I decided to learn a new computer language. I didn't speak any scripting language and was also interested in learning how to write GUIs and to display things graphically. I knew that Python had a Tk library, and overall, for me, Python looked like the best choice.

Some quotes from the Python site:

Python is a remarkably powerful dynamic programming language that is used in a wide variety of application domains. Some of its key distinguishing features include:

• very clear, readable syntax
• strong introspection capabilities
• intuitive object orientation
• natural expression of procedural code
• full modularity, supporting hierarchical packages
• exception-based error handling
• very high level dynamic data types
• extensive standard libraries and third party modules for virtually every task
• extensions and modules easily written in C, C++
• embeddable within applications as a scripting interface

What more could I ask? It's great!
