Binary python extensions with Free Pascal Compiler

Hi all I want to write python extensions with FPC (Free Pascal Compiler, http://www.freepascal.org). In Delphi, this is trivially easy due to the great work of the P4D (Python-for-Delphi, http://mmm-experts.com/) guys; however, when aiming for cross-platform binary extensions, that strategy nat

Re: Counting nested loop iterations

Hi Derek I went for an embarrassingly long time without knowing about "enumerate()". It doesn't directly answer your question about counting *within* nests, but I am going to tell you this on the off chance you don't know yet (and apologies if you do): This: count = 0 for animal in zoo: a =

Re: Binary python extensions with Free Pascal Compiler

I posted this a few days ago. According to the website (http://mmm-experts.com/VersionHistory.aspx?ProductId=3), FPC support has been added since version 3.29. -- http://mail.python.org/mailman/listinfo/python-list

Re: Binary python extensions with Free Pascal Compiler

Well, there it is: * Added support for Free Pascal Compiler (http://www.freepascal.org/) and Lazarus Project (http://www.lazarus.freepascal.org/) Thanks to Michiel du Toit ([EMAIL PROTECTED]) That was easy. I just saw the new support for D2k6 recently. thx Ravi Caleb -- http://mail.python.or

Re: Other languages for PVM

I did not mean the lack of interest on part of the developer. That was explained here. http://www.livelogix.net/logix/future-work.html His complaints were Efficiency and Security. I was wondering why the Python community did not show interest in this. There is tremendous potential in this product.
