  • Python Success Stories

    Python Success Stories Introduction The Blind Audio Tactile Mapping System (BATS) seeks to provide access to maps for the blind and visually impaired. Our goal is to devise ways to present traditionally visual information to the user's other senses. The need for this project became clear when Jason Morris came to the University of North Carolina at Chapel Hill to study Classics. Morris works at the Ancient World Mapping Center (AWMC), a foundation to advance the field of ancient studies with ...

  • Python Success Stories

    Python Success Stories Introduction This article shows how I integrated Python, COM, DocBook, OpenJade, and Word together to create a documentation tool for BEACON, a visual programming environment. This documentation tool was used for code reviews in the software development methodology at my company, and led to significant (>$1M) in cost savings. Before starting this project, I had no prior experience using SGML, XML, or other document markup languages. It was only when I was perilously ...

    Python Success Stories First published in Linux Journal, May 2000. Copyright 2000 Specialized Systems Consultants, Inc. All rights reserved. Introduction My first look at Python was an accident, and I didn't much like what I saw at the time. It was early 1997, and Mark Lutz's book Programming Python from O'Reilly & Associates had recently come out. O'Reilly books occasionally land on my doorstep, selected from among the new releases by some mysterious benefactor inside the organization u...

  • EDU-SIG: Python in Education

    EDU-SIG: Python in Education EDU-SIG: Python in Education More and more, Python is making inroads at all levels in education. Python offers an interactive environment in which to explore procedural, functional and object oriented approaches to problem solving. Its high level data structures and clear syntax make it an ideal first language, while the large number of existing libraries make it suitable to tackle almost any programming tasks. Edu-sig, through its mailing list, provides an infor...

This is not a full reopening of the Grants Program as it existed before. Rather, it's what the PSF is sustainably able to offer right now, given where we stand financially and operationally. The PSF Board, PSF Staff, and PSF Grants Work Group (GWG) are deeply passionate about the program and understand how important it is ...

Release date: 08-FEB-2005 Core and builtins Partially revert the fix for #1074011; don't try to fflush stdin anymore. Library Applied a security fix to SimpleXMLRPCserver (PSF-2005-001). This disables recursive traversal through instance attributes, which can be exploited in various ways. Bug #1114776. Applied a fix to the copy.py fix in 2.3.5rc1 to deal with types that don't hav...

    ...comprehensions and further improves their performance (about 35%). Implemented rich comparisons for floats, which seems to make comparisons involving NaNs somewhat less surprising when the underlying C compiler actually implements C99 semantics. Optimized list.extend() to save memory and no longer create intermediate sequences. Also, extend() now pre-allocates the needed memory whenever the length of the iterable is known in advance -- this halves the time to extend the list. Optimized list res...

  • Computer Programming for Everybody

    Computer Programming for Everybody Computer Programming for Everybody This is the text of a revised funding proposal that we sent to DARPA in August 1999. In March, we heard that at least an earlier version of the proposal was accepted by DARPA; the work has begun late 1999 and will hopefully last two years, although we've only received funding for the first year (through October 2000). We're keeping our fingers crossed for the rest. Unfortunately, the move of the Python developm...
