Lazy streams using generators

This class allows you to use generators as more list-like streams. The chief advantage is that it is impossible to iterate through a generator more than once, while a stream can be re-used like a list. ...

Case insensitive Dictionary

Case-insensitive Dictionary script is a dictionary that has case-insensitive keys. An internal dictionary maps lowercase keys to (key,value) pairs. All key lookups are done against the lowercase keys, but all methods that expose keys to the user retrieve e lowercanal keys. ...

Finite State Machine FSM

This script shows a Finite State Machine (FSM) that can be used for small parsing tasks. The code is quite simple. The bulk of it is comments. In addition to state this FSM also maintains a user defined "something". This "something" is effectively memory, so this FSM could be considered a ...

Basic Linear Algebra Matrix

This script defines the Matrix class, an implementation of a linear algebra matrix. Arithmetic operations, trace, determinant, and minors are defined for it. This is a lightweight alternative to a numerical Python package for people who need to do basic linear algebra. Vectors are implemented as 1xN and Nx1 matricies. There is ...

List iterator with advance and regress

The basic iterator for a list doesn't allow one to skip forward (except with "continue"), or backward (at all), nor does it behave well if the list is modified while it is being traversed. This script is NOT the be-all and end-all of improved iterators, but it gives a few ideas of how a ...

Binary search in one line

This is an implementation of the binary search algorithm in (almost) one line. Given a number 'n' and a list 'L', the function returns the index of the number on the list, or -1. ...
