tkinter and visual ocx
I've managed to register succesfuly an oxc with makepy and my python programm reconises the ocx. But now i have a problem to place the ocx on a tkinter frame. Perhaps somebody could show me a code snippet how to do it ? tia Rony -- http://mail.python.org/mailman/listinfo/python-list
Re: Ruby/Python/REXX as a MUCK scripting language
Rexx", to enable reflection and discussion of the language and its interesting concepts, cf.: <http://prog.vub.ac.be/~wdmeuter/RDL06/Flatscher.pdf>. At the end of the paper there are a few, but actually quite impressive nutshell examples, demonstrating the ease and power of ooRexx in different environments. - Ad prospects of ooRexx: ooRexx is actively being developed and enhanced. The RexxLA has been organizing a yearly "International Rexx Symposium", the 2007 symposium to probably take place in Tampa, Florida, USA, from April 29th, 2007, through May 3rd, 2007. Maybe you or your partners may want to stop by there (the conferences are rather personal, you get to meet everyone in person who has been actively developing ooRexx and ooRexx applications)? 8-)) Again, if you have any questions, please post them. Regards, ---rony P.S.: I have been using ooRexx in classes introducing MIS students to oo-concepts and programming, such that "enduser-programmer" kind of people can successfully deploy their acquired skills to automate/remote-control/script Windows, Windows applications, but also Java and Java applications and applications like OpenOffice/StarOffice possessing Java interfaces. As a matter of fact, such students become able to create scripts to drive e.g. OpenOffice which run unchanged e.g. on MacOS, Linux and Windows, which is actually very cost-effective and impressive, if one thinks about it! -- http://mail.python.org/mailman/listinfo/python-list
Creating a PYD file

Re: Creating a PYD file
Sorry that was a typo... The question actually is, is a PYD file created from C faster then a PYD file from Pyrex ?

A question to experienced Pythoneers
Here's the story : I've been hired by a company as a consultant to reorganise there development department. The actual situation is : The manager of the development has been fired, main reason (what they told me) is that they have big big troubles in keeping deadlines ! For there last product, for which they estimated 3 man years of development they had 9 months extra effort, and the product was delivered a year to late. I basicaly have 'carte blanche' :) One of my plans is to introduce Python as development tool. They mostly develop back-office software, and at the moment they do it all in C with MFC. Another new requirement they have, is that the new product should run on Win & Mac. So, my strategie would be : - Use Python and wxpython for the GUI - Develop critical routines in Pyrex or in C and make PYD's from it which will be imported by the main Python programm. - Distribute with py2exe on Win & py2app for Mac. What do you think of this ? Another point of attention is that the software isn't Open Source, it is a commercial package. So protection of sources is important. Now I know that anything can be decompiled, even C. The only question is, how hard is it and how much effort must someone do to decompile and retro engineer code to understand it. I think by putting all program logic in Pyd files that I would be quite secure ? On a side note : Is it harder to decompile PYD files then PYC files ? I allready had a meeting with the developpers and did a presentation of python with wxwindow, mostly with an open source project where I contribute to the development. They didn't see any big problems to learn Python fast and they allready know C. All opinions, advice here is welcome :) Tia Rony -- http://mail.python.org/mailman/listinfo/python-list

Project organisation
Imagine I have x projects and they all use util.py What would be the best way to organise this 1. c --\project1\*.py | |-\project2\*.py | --\globals\util.py This organisation has the problem that if I have to modify something to util.py that I need in project2, I'll have to retest project1 to make sure it still works (that could be project 1..n). 2. A copy of util.py in each project directory ? The advantage is that I can modify each util.py in function of the need of the project but it looks clutered, having n versions of util.py.

Missing rotor module
I'm in the midle of porting a python 1.5 application to 2.4 I just discovered that the rotor encryption module isn't part anymore of the 2.4 distribution.

Re: combining a C# GUI with Python code?
Isn't it a bit overkill to implement the whole .net framework 'Just' for a GUI ?? If you want to build quickly nice GUI's for your python program, have a look at wxpython & wxdesigner Rony > Is it possible to construct a C# form (using Visual Studio) but write only > Python code for the events?

Re: Python Programming Books?
Since I'm a professional developper,I don't think that my personnal view on those books would be of any use to you. I actually have no idea how to start Python if you're not a developper, I know it is possible since quit a lot of matimatical engineers use it. But I'm sure some people here will give you good advise. > Thanks, if you don't mind could I have a small personal > description on the quality of the books (pros, cons). > > I also am interested if anyone has used "Python Programming: An > Introduction to Computer Science" and if I could be given a detailes > evaluation about it. > > Thanks again. -- --- Rony Steelandt BuCodi rony dot steelandt (at) bucodi dot com Visit the python blog at http://360.yahoo.com/bucodi -- http://mail.python.org/mailman/listinfo/python-list
Re: Python keywords vs. English grammar
I'm not a english speaker, so I just accepted it...;
I understood it as :
'Try' allways to execute this code, 'except' when it doesn't work do
this
