Re: Advice on how to get started with 2D-plotting ?
Wow, what an impressive turnout ! Thanks a lot, rantingrick, CM and Herbert, for the fast answers, useful tips and especially the sample code ! Beats starting from a blank page, with a big stick, and will certainly set me on my way much faster... networkx does seem a bit over the top for my simple goal, but both the Tk (I always forget Tk !) and Matplotlib approaches seem to fit the KISS principle just fine... on to the tinkering now :-) Again, thanks to all ! fp -- http://mail.python.org/mailman/listinfo/python-list
Advice on how to get started with 2D-plotting ?
Hi, I'm a Python long-timer, but I've never had to use tools like Matplotlib & others before. Now, for my work, I would need to learn the basics fast, for a one-time quick-n-dirty job. This involves a graphic comparison of RFC1918 IP subnets allocation across several networks. The idea is to draw parallel lines, with segments (subnets) coloured green, yellow or red depending on the conflicts between the networks. What would be the simplest/fastest way of getting this done ? (the graphic parts, the IP stuff I know how to handle) Alternately, if someone knows of a ready-made and accessible tool that does just that, I'm all ears :-) TIA, fp -- http://mail.python.org/mailman/listinfo/python-list
Re: What do you use with Python for GUI programming and why?
Robert said : > Is there a push to one toolkit or the other? If you are just now getting started, I would honestly suggest you save a whole lot of time and dive straight into PyQt. I've tried most 'em over the years (including some now discontinued), and in my experience Qt is way above the rest, especially as far as consistency and productivity are concerned. The Python bindings are very mature and well maintained, and go a long way attenuating the evil C++ roots. I havent tried Nokia's equivalent (PySide). I'm not sure what its fate will turn out, given the company's change of heart and Microsoft honeymoon. At least PyQt is't going anywhere soon.

Thanks to Mark and Christian : dependency-walker confirmed the VC++ issue. After installing the MS redistributable DLL package -- actually I had to install *three* before hitting the right one (2005SP1) -- libpyexiv2 finally loads all its dependencies.

John Henry <[EMAIL PROTECTED]> said : > Welcome to the modernized world of Pythoncard!!! Hey, that's really neat ! I remember dabbling in Pythoncard in the early days, some years ago, it was a very interesting project. I gave it up eventually, partly because it seemed somewhat abandoned (I see it's still stuck in 2006 ?), but mostly because the wxPython dependency was either unavailable or too hefty for the sort of machines I was interested in using it on (a Sharp Zaurus then, now Nokia Internet tablets). Since then I've been doing web apps instead, hosted and used on the devices themselves. So using Pythoncard as a designer for web apps, of course that rings a bell... Do you have any idea of the computing requirements of Qooxdoo and QxTransformer, compared to a native Pythoncard app ? I wonder if your stuff would run acceptably on today's mobile platforms (the Nokias have a Firefox derivative that is reasonably competent at javascript), and would give it a try if it's not too arcane.

Looking for a particular http proxy...
Hello, I would be grateful if someone could point me to an existing and working http proxy implementation that satisfies the following requirements : - as small and simple as possible, ideally no dependencies outside python - easy to customize (for controlling outgoing http headers for instance) - supports chaining to another remote proxy I have spent some time on the list at : http://xhaus.com/alan/python/proxies.html ...but haven't found what I need yet : Some old pages/packages have broken links ; some are too full-featured and/or have heavy dependencies (xml, ssl, twisted etc.) ; some have remote proxy support but are complicated enough that I'm not sure where to hack at the request headers ; and the really simple ones don't chain to other proxies. Actually "Tiny HTTP Proxy" and its derivatives would be just fine for what I want to do, but I don't know how and where to add remote proxy support. I did get httpMonitor to work (although it is overkill), but it depends on PyXML (still 900 KB even pared down some), and it seems to have some strange side effects on the browser.
