  • What's new in Python 1.5 and beyond

    What's new in Python 1.5 and beyond If you download the source release, there's a loooong list of changes since release 1.4 in the file Misc/NEWS. Below are some highlights. (Or go directly to the listings of what's new in 1.5b1, what's new in 1.5b2, and what's new in 1.5 (final).)

    Towards a Standard Parser Generator Towards a Standard Parser Generator Martin v. Löwis Humboldt-Universität zu Berlin Institut für Informatik loewis@informatik.hu-berlin.de Abstract Developing parsers for "little" languages is a common task for many software developers. People have frequently requested inclusion of a specific parser generator framework into the Python library. In this paper, we compare several Python parser generators, using the XPath langua...

  • Parade of the PEPs

    Parade of the PEPs Parade of the PEPs To start off Developer's Day at the Python10 conference I gave a keynote ending in what I dubbed "the parade of the PEPs". It was a brief overview of all open PEPs, where I gave my highly personal and subjective opinion for each PEP. Later, I realized that this might have been of interest to other developers. I didn't take notes at the conference, so below is a different set of comments that I created from scratch during a single two-hour sitt...

    ...read() has a new argument chars which specifies the number of characters to return. codecs.StreamReader.readline() and codecs.StreamReader.readlines() have a new argument keepends. Trailing "n"s will be stripped from the lines if keepends is false. The documentation for doctest is greatly expanded, and now covers all the new public features (of which there are many). doctest.master was put back in, and doctest.testmod() once again updates it. This isn't good, because every testmod() c...

CNRI has placed an open source license on this version.

  • IDLE and tkinter with Tcl/Tk on macOS

    IDLE and tkinter with Tcl/Tk on macOS Important If you are using macOS 12 Monterey or later, you may see problems with file open and save dialogs when using IDLE or other tkinter-based applications. The most recent versions of python.org installers (for 3.10.0 and 3.9.8) have patched versions of Tk to avoid these problems. They should be fixed in an upcoming Tk 8.6.12 release. If you are using a Python from any current python.org Python installer for macOS (3.10.0+ or 3.9.0+), no further acti...
