Python Wrappers on Databases and Datatypes/Data Structures

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.

• xlrd (for old excel files in tableloader.py)
• openpyxl (for new excel files in tableloader.py)
• bsddb (speeds up filedbwrap; don't use this addition for production code -- requires very expensive oracle license)

Download xlrd from http://pypi.python.org/pypi/xlrd

cd <xlrd directory>
[sudo] python setup.py install

Download hjunes-openpyxl (python version fixes) from https://bitbucket.org/hjunes/openpyxl/downloads

cd <openpyxl directory>
[sudo] python setup.py install

Once the dependencies are resolved the package requires no other installation processes.

• File based dictionaries and sets
• Persistent file based objects
• 2D table loading/saving
• Table wrappers to transpose and transform data
• List wrapping for sublist selection (without copying)
