Mandelbrot Set made simple (Python)

2015-12-28T17:56:08-08:00

Python recipe 579143 by Jack Trainor (educational, fractal, graphics, mandelbrot, mathematics). Revision 2.

This is a mini-framework for exploring the Mandelbrot Set.

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.

See module documentation for further information. Compatible with Python 2 and 3.

"More Sex is Safer Sex" Paradox (Python)

2010-09-22T02:56:37-07:00

Python recipe 577403 by Jack Trainor (educational, simulation).

In his book, "More Sex Is Safer Sex: The Unconventional Wisdom of Economics, " Steven Landsburg argues that if sexual conservatives took more sexual partners it would improve everyone's chances of finding low-risk partners, thereby reducing the spread of STDs for all.

See http://www.nytimes.com/2007/07/08/books/chapters/0708-1st-land.html?_r=1&pagewanted=print .

This recipe attempts to simulate the scenario which Landsburg describes and test his claim that "More sex is safer sex."

TRAC Interpreter -- Sixties programming language (Python)

2010-08-22T19:05:09-07:00

Python recipe 577366 by Jack Trainor (algorithm, educational, interpreter, language, trac).

A Python implementation of an interpreter for the TRAC programming language developed by Calvin Mooers in the early 1960s. This implementation reconstructs Mooers' original algorithm in Python and supports only a limited number of TRAC primitives for demonstration purposes.

TRAC Interpreter - Dragon style (Python)

2010-09-20T00:42:21-07:00

Python recipe 577396 by Jack Trainor (algorithm, educational, interpreter, language, lexical_analyzer, trac).

I've rewritten the TRAC interpreter from Recipe 577366 using a modern recursive descent style based on the Dragon book's lexer/parser model at the end of "Compliers: Principles, Techniques and Tools," Chapter 2, by Aho, Sethi, Ullman (1986).

Python 2.7 Linked List vs List (Python)

2010-08-13T04:05:42-07:00

Python recipe 577355 by Jack Trainor (educational, list).

Linked list implementation based on Python 2.7 collections.MutableSequence with a few benchmarks comparing the linked list with the built-in list type.

2010-09-20T01:16:07-07:00

Python recipe 577397 by Jack Trainor (algorithm, educational, interpreter, language, lexical_analyzer, trac).

This is my third and final version of the Trac Interpreter from Recipe 577366. It processes the character stream into appropriate class objects and stores these objects on a stack.

Python recipe 577327 by Jack Trainor (educational, framework, oop, simulation). Revision 2.

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.
