Revision 2. </p> <p>This is a mini-framework for exploring the Mandelbrot Set.</p> <p>It outputs to a Tkinter window or to a PNG file (Pillow package required). It includes a disk caching mechanism for saving and later retrieving Mandelbrot calculations to avoid recalculating the Set on each run.</p> <p>See module documentation for further information.

Revision 2. </p> <p>I am adapting Prof. David Cheriton's OO software methodology to Python. It's an approach for building industrial-strength code with a disciplined architecture, consistent naming conventions, and a rigorous division of interface from implementation. I'll be adding more of his techniques in further recipes. These recipes are based on Cheriton's CS249a course at Stanford.</p> Attribute-based Framework 1: Basics (Python) 2010-07-21T21:40:54-07:00Jack Trainorhttp://code.activestate.com/recipes/users/4076953/http://code.activestate.com/recipes/577327-attribute-based-framework-1-basics/ <p style="color: grey"> Python recipe 577327 by <a href="/recipes/users/4076953/">Jack Trainor</a> (<a href="/recipes/tags/educational/">educational</a>, <a href="/recipes/tags/framework/">framework</a>, <a href="/recipes/tags/oop/">oop</a>, <a href="/recipes/tags/simulation/">simulation</a>).
