    ...properties. I quickly fell in love with the language and its community and that led me to become a core dev some years ago. Since I became a core dev I have worked towards making Python faster and more versatile. Although most of my work is in the parser, the compiler pipeline and the garbage collector I like to work all over the place fixing bugs and trying to spot performance improvement opportunities. Hopefully, in the following years, we can push Python forward to the future by improving its...

  • Standard Exception Classes in Python 1.5

    ...properties when used as exceptions, it is desirable to migrate to a situation where classes are used exclusively. Prior to Python 1.5 alpha 4, Python's standard exceptions (IOError, TypeError, etc.) were defined as strings. Changing these to classes posed some particularly nasty backward compatibility problems. In Python versions 1.5 and later, the standard exceptions are Python classes, and a few new standard exceptions have been added. The obsolete AccessError exception has been del...

    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 ...

Unfortunately, it has been that way since 1997. Even though it looks like PyLR would support a custom tokenizer and that PyLR was capable of dealing with the original XPath grammar, it is not clear how exactly to use that tool, given the scarce documentation. Furthermore, the author reports that ...
