Grouping objects into disjoint sets

This class provides a lightweight way to group arbitrary objects together into disjoint sets when a full-blown graph data structure would be overkill. Objects can be joined using .join(), tested for connectedness using joined(), and all disjoint sets can be retreived using get(). The objects being joined must be hashable. ...

High performance currying with instance method

This script implements the instance method for performing currying. Instance method provides a way to perform currying such that the curried function runs much faster than one produced by closure. Currying is an important technique to build callables on the fly and is well covered in other recipes. If the callables ...

Format number function

For many languages it is possible to use the locale module to format numbers. But there are at least three languages for which the locale.localeconv()['thousands_sep'] is empty: brazilian portuguese - 'pt_br', portuguese - 'pt' and spanish - 'es'. The first function, format_positive_integer() will return the passed integer number as a string ...
