Pythologic Prolog syntax in Python

Some of Python's powerful meta-programming features are used to enable writing Python functions which include Prolog-like statements. Such functions load a Prolog-like database. When coupled with a suitable inference engine for logic databases, this is a way to add logical programming -- the last unsupported major paradigm -- to Python. This ...

Python Octree Implementation

This script is a simple implementation of an octree data structure in python. Its use is primarily for fast collision or view frustrum culling in interactive 3d environments, but its possible uses are quite open-ended. It was originally written for use with the pyOgre 3d engine binding. The code makes use of ...

Rabin Miller probabilistic prime test

In this script is included a method for performing the Rabin-Miller probabilistic test for a composite witness.  Rabin-Miller test can only tell us if a value is definitely composite. In the case where a test value is not a witness for the compositeness of a potential prime, it can only lie with a probability ...

Read write object for pkg config files

The PkgConfig class is useful by itself. It allows reading and writing of pkg-config files. This file, when executed, will read a .pc file and print the result of processing. The result will be functionally equivalent, but not identical. Re-running on its own output should produce identical results. ...

Readable switch construction

Python's lack of a 'switch' statement has garnered much discussion and even a PEP. The most popular substitute uses dictionaries to map cases to functions, which requires lots of defs or lambdas. While the approach shown in this script may be O(n) for cases, it aims to duplicate C's original 'switch' functionality ...

Rebind class properties

Sometimes you define properties in base class and override the getter setter methods in derived classes. Then you find out the base class though has derived properties are still pointing to baseclasse's methods not the overriden ones. ...

Remove duplicates from a sequence

The fastest way to remove duplicates from a sequence depends on some pretty subtle properties of the sequence elements, such as whether they're hashable, and whether they support full comparisons. This script defines the unique() function that tries three methods, from fastest to slowest, letting runtime exceptions pick the best method available for ...

Restrictive APIs for Python

Python has no inherent provision for a restrictive API that blocks accesses to methods and variables outside an allowed set. Inexperienced Python programmers may fail to adhere to an agreed-upon API, directly accessing the private internals of a class. Adherence to defined APIs is a good thing. This script contains a  ...
