<p style="color: grey"> Python recipe 579143 by <a href="/recipes/users/4076953/">Jack Trainor</a> (<a href="/recipes/tags/educational/">educational</a>, <a href="/recipes/tags/fractal/">fractal</a>, <a href="/recipes/tags/graphics/">graphics</a>, <a href="/recipes/tags/mandelbrot/">mandelbrot</a>, <a href="/recipes/tags/mathematics/">mathematics</a>). 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. Compatible with Python 2 and 3.</p>

This implementation reconstructs Mooers' original algorithm in Python and supports only a limited number of TRAC primitives for demonstration purposes.</p>

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>
