PDO (Python Database Objects), is a collection of objects for use with Phase or with the Python programing language. PDO is designed to be robust and simple at the same time, allowing access to multiple styles of databases with one set of instructions. This means never having to worry again about your syntax when changing database platforms on your next project. PDO provides an object oriented API similar in intent to ADO and JDBC.
PyORBit is a Python binding for the ORBit2 CORBA ORB. It was developped to suit the needs of the bonobo bindings in GNOME-Python, but is usable for other purposes as well. It aims to follow the standard Python language mapping for CORBA. It can generate stubs at runtime from typelibs, IDL files, or by introspecting remote objects using ORBit2's IModule typelib capabilities.
python-stablesort is an adaptive, stable, natural mergesort. It is a back-port of the new Python 2.3 stable listsort algorithm to all Python versions (tested with all versions from 1.5.2 to 2.2.3). It can also be regarded as some sort of forward-port in case the default Python list sort() method will change to a non-stable algorithm in the future again.
