A Journey to Python by Alex Martelli, 2006 recipient of the Frank Willison Award After a quarter century of experience in programming (once as a sideline of my main job as a hardware designer, at Texas Instruments and IBM Research, but as my main job for over half that time, at IBM Research and Cad.Lab/think3), I finally stumbled upon Python in 1999. This was thanks to the kind nagging of a friend and colleague whose judgment I respected and to whom I still feel grateful for his insistence (A...

Python Patterns - An Optimization Anecdote Warning This page stays here for historical reasons and it may contain outdated or incorrect information. The other day, a friend asked me a seemingly simple question: what's the best way to convert a list of integers into a string, presuming that the integers are ASCII values. For instance, the list [97, 98, 99] should be converted to the string 'abc'. Let's assume we want to write a function to do this. The first version I came ...

Built-in Package Support in Python 1.5 Built-in Package Support in Python 1.5 Starting with Python version 1.5a4, package support is built into the Python interpreter. This implements a slightly simplified and modified version of the package import semantics pioneered by the "ni" module. "Package import" is a method to structure Python's module namespace by using "dotted module names". For example, the module name A.B designates a submodule named B in a package named A. Just like...
In 2004, the PSF selected three grant proposals to fund. One of them, "Moving Jython Forward", was only partially completed by Brian Zimmer due to a job change. Some time later, Frank Wierzbicki offered to take over maintenance of the Jython project, but he found that he had under-estimated the amount of work necessary when taking over the proposal from Brian, and he did not make as much progress as he had wanted to. Martin von Löwis, the Grants Committee chair, has since discuss...
