Tools for wrapping data and manipulating it in efficient ways

Project description

Python Wrappers on Data Structures and abstractions over persistent data stores.

Description

This module is a home for Python wrappers of data, databases and datastructures. It defines common use wrapping that can treat one style of data as another or reorder/subselect a collection.

The filedbwrap file defines many file based database objects such as dictionaries and sets which are treated as memory objects in Python but have a very large capacity with limited memory footprint.

The savable file defines object persistence objects which save state when they deconstruct and reload that state upon initialization.

The listwrap file defines a no-copy list subset selector that can retrieve subsets of data to be treated as complete, contiguous lists.

There are also some file loading/saving modules for various formats.

Dependencies

  • allset

  • xlrd (for excel files in tableloader.py)

  • redis (for RedisDB wrappers)
