Contracts for Python

Contracts for Python is a Python implementation of a concept that comes from the Eiffel language, Design by Contract. Programming by Contract allows a programmer to document a function/class with statements describing behavior." Along with the regular code, contracts for functions and methods add pre and post condition checking, and code for testing correct operation of the code.

A draft Python language PEP (Python Enhancement Proposal) for Design by Contract has been submitted. The status of PEP 316 is currently Deferred.

The PEP states that compared to Assertions, Contracts produce better documentation, and make for easier testing.

The Eiffel Design by Contract document goes into greater detail on the subject:

Version 1.0 beta 3 of Design by Contract just came out. The CHANGELOG file details the recent changes, which include support for Python 2.2 and Jython among other things.

The June 18th 2003 PostgreSQL Weekly News is out. "After last week's mention of running PostgreSQL on an Opteron with Debian Linux in 64-bit node, I received a couple of emails about other people using PostgreSQL on 64-bit hardware. One in particular was a note that SuSE Linux Enterprise Server 8 for AMD64 has been shipping with support for PostgreSQL 7.2.4 since April, and is actively being maintained. With that said, we are now less than two weeks away from feature freeze (July 1st). Bruce Momjian has gone through a number of patches, if you plan to add something new for the next release it needs to be submitted as soon as possible."

CSS 3 Selectors (O'Reilly)

As with all W3C standards, there is the lengthy discussion process conducted by the related working group, then the problem of implementation by web browser vendors, and finally the unpredictable period of time for people to update to new versions of their browser. These steps can take a year or two each."
