Hope others find this article helpful and relevant: http://www.eweek.com/developer/open-source-python-code-sets-new-standard-for-quality-study.html/?kc=EWKNLEAU09102013BESTOF2&dni=77668545&rni=22939981 A development testing company (Coverity) reports that the core Python platform has a very low number of source code defects and its developers effect repairs to known flaws very readily, as compared to other open-source projects. I can't attest to the validity of the claim (one way or the other), but it is something worth noting -- https://mail.python.org/mailman/listinfo/python-list
About Embedding PyWin or wxPython
Folks: I want to embark on a project to add Python (actually, wxPython or PythonWin) to a new Windows app I want to start writing soon. Essentially, I want to take VB6 (or pos Delphi) and construct the app framework/core functionality using one of those languages, then extend the app w/ Python, the same way one can extend the MS Office apps using VBA. The core Python docs provide the fundamental info one needs to get started. But, I've been looking for some pointers to articles/web pages that will bootstrap the effort, so I won't have to completely reinvent the wheel. So far, the c.l.p ngroup traffic (and the web in general) that speaks to this subject is apparently pretty sparse. Since I'm a one-man show, it would be helpful if anyone could offer pointers to sites/pages/books that address some of these issues: 1) To COM or not ? From an implementation standpoint, it seems worthwhile to build the host app as a series of COM objects, which could then be ref'd/manipulated via external Python code. Not sure if this makes sense from a performance-perspective, but I doubt the apps I'm thinking about (mostly desk accessory utils kinda, sorta) are going to be compute-intensive at all. 2) SWIG or not ? Have never used it, but know that SWIG has been ref'd many times in the ngroup as an tool for facilitating the use of Python as an embedded language. Is SWIG worth the effort for a relatively small (<10 KLOC) app ? 3) Handling exceptions. I want to start from Day One with a sensible approach to debugging and testing both host objects and external scripts. 4) Deployment. Size (30 - 50MB for wxPython or PyWin alone) and a silent install of either pkg prior to installing the host app. Regardless of the conversation in this group, I plan to get started in the next few days. This is how I'm currently looking at the above issues: 1) COM: Yes, since COM seems like an easy fit w/o writing lotsa glue code because of built-in support via PyWin 2) SWIG: Not for a 1st cut, at least not to get one's feet wet, so to speak 3) Exceptions: No clue. Need to closely read Extending/Embedding Python for more guidance 4) Deployment: Bite the disk space bullet and use PyWin or wxPython as is Anyway, that's the beginning of the conversation. If you have any observations or suggestions, please feel free. Later...MR -- http://mail.python.org/mailman/listinfo/python-list

Steve: Thanx for reminding me. I have that book around here *someplace*. Never finished it, but will dig it out pronto. As you so aptly point out, I want to develop more than experiment and who better to learn from than the author of PyWin itself Steve Holden wrote: > You almost certainly would regard a copy of Hammind and Robinson's > "Python Programming on Win32" as remarkable value for money.

Re: About Embedding PyWin or wxPython
Simon: Good idea, but I'm not yet .NET-compatible and can't handle that learning curve in addition to everything else. IronPython is an option I hadn't considered, but yours is a good idea for the next project Simon Hibbs wrote: > Have you considered IronPython? > > This is of course only an option if you're prepared to code in VB.NET > or C# instead of VB6 or Delphi, but it would provide seamless > integratioon between your Python code and the rest of your app and > would not require an external graphics library - although you would > need to distribute the .NET and IronPython runtimes. -- http://mail.python.org/mailman/listinfo/python-list
Re: About Embedding PyWin or wxPython
Phillipe: Actually, it's not performance of the core app that concerns me. I'm thinking more about UI/form *design* productivity. I've done a lot of Access work over the years and while the stand-alone VB form designer isn't quite as thorough, it's still one of the slickest out there. Unfortunately, there's no designer for PyWin and wxPython's XRC is nice but not in the same league as what can be done w/ Delphi or VB. Yes, I'm aware that wxWidgets has a real form designer, but that's yet another story, for another day. Making XRC into a more fully-featured tool (more on par w/ the aforementioned) is a way nice project unto itself, but not right now. However, the desk accessory I've mentioned is an excellent 1st step towards *possibly* doing something much bigger Philippe Martin wrote: > Do you have major performances issues ? why not write everything in > Python/WxPython ? > > > I used to write my applications in VB6 with python com objects ... and > decided there was no gain there. > > Regards, > > Philippe -- http://mail.python.org/mailman/listinfo/python-list
Simple Char-I/O Dialogs for Win32 and DOS
Folks: I've already searched the group and have determined there *are* char I/O based input systems, ala NCURSES, that are Python-compatible (ie. PyNCurses, UrWid, etc.) What I *need* is something that does simple dialogs under char-I/O Win32 and DOS w/ very little fuss or muss. At most, I need one or two dialog boxes to boot my little app/util *AND* hope upon hope I don't need port something (which would take more days than I have *and* would also require a non-trivial support effort from a one-man show: *me*) and can simply grab something (open-source) off-the-shelf. I don't need a dialog/forms designer, no database access, just a basic dialog box to get input from a couple of text boxes, check boxes, etc. Does such an animal exist and can someone offer a link to the kit ?

[Q] About an Installer Script for PyWin
I need PyWin under the covers, that is, to install it as part of an application, but in such a way that it isn't visible to users. I'm concerned about a so-called "power-user", seeing the Python directory and/or the corresponding entry in the 'Add/Remove Programs' list, breaking my app by uninstalling what he/she thinks is removing an 'unnecessary program.' Unfortunately, I don't see any installer scripts, like for Inno Setup or NSIS in the source archive I just downloaded from SourceForge. I'd love to volunteer to do something like this for the larger community of Pythonista, but I can't find any info (via Google) about this. AFAIK, the critical info is related to the registry settings for the Win32-related elements. I'm especially concerned about installation of the COM infrastructure, as getting the other registry settings is mostly tedious (but doable), trial-and-error exports from the Registry. The rest "should" be simply a matter of creating the primary directory structure and copying the archive files to it. Does anyone have pointers ?
