  • Python Success Stories

    ...started our project we was very proficient in Perl and completely unaware of Python: so we chose Perl. We discovered Python when we decided that we had to substitute the PerlTK user interface with a Web-based one. We found Zope, and after some attempts to integrate Perl with Zope, we switched to Python. To make a log story short, at the end we dropped Zope but kept using Python (and rewrote the whole Devil Framework with it). Without this fortunate switch we think the Devil Framework would not b...

  • Python 2.4.1 - Release Notes

    ...without arguments now returns False rather than raising an exception. This is consistent with calling the constructors for the other builtin types -- called without argument they all return the false value of that type. (SF patch #724135) In support of PEP 269 (making the pgen parser generator accessible from Python), some changes to the pgen code structure were made; a few files that used to be linked only with pgen are now linked with Python itself. The repr() of a weakref object now shows t...

Lexical Analysis Most scanner generators use regular expressions to describe tokenization. Even though all the parser generators described in this paper do support tokeniz...

    ...with elegance and consistency, and as a result, > the design has held up well. Sorry, but I need to disagree with everyone. Not that I have an opposing view formed, this is just a matter of principle with me. I'll let you know what my view is once I figure it out -- it seems unusually hard to disagree with everyone here without appearing inconsistent! Tempted to point out that Perl and Tcl are both more widely used than Python, but I don't want to get involved with facts lest they turn on ...

  • Computer Programming for Everybody

    ...with a far-ranging impact that can barely be anticipated or imagined. On a shorter term, the quantity and quality of available computer software will improve drastically, as the imagination and labor of millions is applied to the problem. Inventive users will be able to improve the software that supports them in their tasks, and share their improvements with their colleagues or--via the Internet--with others far away who are faced with the same tasks and problems. The ability to modify or ...
