Re: Pros/Cons of Turbogears/Rails?

Ruby/Rails seems to have been mainly *nix until fairly recently. Sometimes the Windows version of a module or tutorial will lag significantly. (ldap comes to mind.) Sometimes Windows-oriented questions get pretty short shrift along the lines of: Perish the thought! or Why would you? instead of serious treatment. It's not a deal-breaker and neither community is perfect in this respect. I now work mostly with Ruby/Rails, but I did Python/CherryPy for quite a while, and that's my impression.

Re: MS word document generator
You might also consider OpenOffice, which writes to ODF. That way, you're working to a standard. You can script OpenOffice in Python (http://udk.openoffice.org/python/python-bridge.html) . OpenOffice can save in .doc, and does a pretty good job of making a file that most MS Word versions will render properly. According to http://opendocumentfellowship.org/Devel/LibOpenDocument, there is a Python API in development, but I don't know how far along they are. ODF isn't too bad to hack, if you need to do that.

Re: Please, I Have A Question before I get started
Well, Nicholas Chase just posted an OpenLaszlo tutorial/app that shows how OpenLaszlo handles sounds. Try http://www-128.ibm.com/developerworks/edu/os-dw-os-php-openlaszlo1-i.html You have to register, but it's free, and they don't bug you. It's PHP driven, but that part's easily ported to Python. Anyway, there's the basis of an all open-source or freeware application that animates with sounds. Ron -- http://mail.python.org/mailman/listinfo/python-list
Re: Please, I Have A Question before I get started
Since you are comfortable with HTML, you could use the browser as your GUI, and use a lightweight python server like Karrigell (or CherryPy, or Turbogears) to serve the pages. A little javascript to move the highlighting around, and . . . Well, frankly, it's still harder than it ought to be. (I agree with Steven, it sure seems like it has been long enough.) It's not totally dreadful, though, and it is free. Ron -- http://mail.python.org/mailman/listinfo/python-list
Re: Please, I Have A Question before I get started
Well, there's OpenLaszlo, which handles the sounds/animation for http:www.pandora.com, I understand. It may be overkill for a desktop app, but it's free. It was originally written in Python, I think, but it uses ECMAScript for scripting. It's free, and reportedly handles sounds and animations, and isn't too hard to program.

Re: Write a GUI for a python script?
If you are already familiar with html, you might consider using the browser for the UI. It's pretty much cross-platform, if you ever need that, and users are accustomed to browser look/feel. If your installation doesn't already have a python-enabled http server running, there are several options (python CGI scripts, cherrypy, kerrigell), any one of which is easier to learn and more generally-applicable (I think) than any of the gui toolkits.

Re: Embedding an Application in a Web browser
From the OP: snipAs for the application it has to be able display simple animated graphics such as circles, lines and squares. However if someone clicks on a shape it should open up another application, such as Word. Thanks, Rod Python Newbie /snip snipThe application itself can sit on the local users computer, rather than actually being downloaded via the web. It will be retrieving data from a variety of sources./snip I was thinking that the security provisions might make it difficult for the script in the browser to interact with the OS. If that is simple to get around, then I agree, Karrigell is overkill. OTOH, Karrigell makes it simple to interact with the local machine's OS, and especially if you are a beginner at Python. YMMV, of course. Thanks for offering your opinion. Ron -- http://mail.python.org/mailman/listinfo/python-list
Re: Embedding an Application in a Web browser
You may already know this, but I don't think anyone has mentioned it explicitly. You can run a Python web server (I like CherryPy) on the local machine, and serve pages to localhost. Everything else is just plain old Python, and talking to the OS is no problem. Ron -- http://mail.python.org/mailman/listinfo/python-list
Re: Embedding an Application in a Web browser
I forgot -- I like the idea of Kerrigell, too. It runs on top of CherryPy, and lets you use python either in the server (which is just a little program on your local machine) or embedded in the html pages, or in a Kerrigell service, which is an application server based on Python. So, a script to print the squares of numbers from 1 to 9 looks like: Python script + print h1Squares/h1 for i in range(10): print %s :b%s/b %(i,i*i) Karrigell service def index(): print h1Squares/h1 for i in range(10): print %s :b%s/b %(i,i*i) HTML Inside Python +++ h1Squares/h1 for i in range(10): %s :b%s/b %(i,i*i) Python Inside HTML +++ h1Squares/h1 % for i in range(10): print %s :b%s/b %(i,i*i) % It's certainly flexible. As far as your animated shapes go, you have a number of unattractive options! Flash (my preference, if you already have the authoring software,) openLazslo (maybe the best bet for free), SVG (which requires a plug-in for IE,) or creating them and making them interactive with Javascript ( see http://www.walterzorn.com/jsgraphics/jsgraphics_e.htm ) Ron -- http://mail.python.org/mailman/listinfo/python-list

Re: How to generate graphics dynamically on the web using Python CGI script?
Steve Holden wrote: Debashis Dey wrote: Hello, I have a python CGI program. I would like to show a graph within a HTML plage. I would like to dynamically generate the graph using the python CGI script on the web server side and send it to the browser. My question is how can I do this in python? Is there a free tool to do this? Can someone please send me some simple python code to draw simple graphics within HTML (e.g. draw a line or a circle). Unfortunately HTML does not include graphics facilities, simply the ability to refer to graphical resources. The typical way to include a created graphic would be: 1. Create a (.png, .jpg, .gif) file showing the image you want 2. Store it in a temporary file whose name will be unique to the current session 3. Generate an HTML response including an IMG ... tag referring to the newly created graphic SVG might be suitable; Firefox supports a reasonable subset of SVG out of the box, and even IE supports it through an Adobe plugin.

Re: Which Python web framework is most like Ruby on Rails?
Wow! You´re right, at least at first reading. It looks REALLY simple, and almost anything you can dream up will work. Python scripts, python-in-html, html-in-python, and karrigell services ( based on CherryPy). Seems to support smart urls, sessions, authentication, and internationalization out-of-the-box. Documentation seems clean, short, and to the point. Has anyone other than Kerrigell himself used it? I think I will use it around the shop for a desktop project just to get the feel of it. I am not sure about the Gadfly db -- fine as a default for development; but I'd need other options for production. My answer to the perennial Python newbie question, What do I use for a GUI (please-please-please-I-hope NOT Tkinter or any derivative thereof)? may change to, Just say 'Kerrigell' and do it in the browser.

Re: Python for Webscripting (like PHP)
Yes the stdlib offers all the basic functions, but why work so hard? Get CherryPy (http://www.cherrypy.org) and relax a bit. You'll be able to concentrate on Python for the backend, HTML for the frontend, without a lot of directory-diddling. Also, check out http://www-128.ibm.com/developerworks/opensource/library/os-cherrypy/index.html#main for a nice, fresh slice. Ron -- http://mail.python.org/mailman/listinfo/python-list
Re: Python for Webscripting (like PHP)
Yes, there's a tutorial about that -- there are several options depending on the URL structure you want to expose, and your version of Apache. None of them are torturous, though.

Re: What is your favorite Python web framework?
Admin: I have kept the following: - PyWork - http://pywork.sourceforge.net (Not sure if it's mature) - Django - http://www.djangoproject.com (Looks interesting) - CherryPy - http://www.cherrypy.org (Unsure) I have also found a more comprehensive list here: http://wiki.python.org/moin/WebProgramming But I'd like to know your opinion on what you think is best. . . . I favor speed of development, intensive OO development, performance under heavy load, short learning curve, good documentation and community. I settled on CherryPy: Performance under load -- can't say one way or the other. I do know it's lightweight -- 40kb download, I recall. Good documentation -- yeah, if you are using the mainstream features. It's pretty extensible, too, so there are some secondary functions and features that are not as well documented. I know that the documentation is a major concern of the oommunity, and that they are pretty quick to respond when the docs are unclear. I give CherryPy very high marks for: speed of development, intensive OO development, short learning curve (if you already know Python), and community. And, as I said, for extensibility. I found I had working apps running on my machine with CherryPy in less time than I needed to read the installation docs on some other frameworks. It's just like writing Python, but with one extra object (cpg (2.0) or cherrypy (2.1) and one extra setting (exposed = True). That's it. I'd say give it a try -- you can have it running apps and go through the tutorials in a morning, so why not get first-hand with it? -- http://mail.python.org/mailman/listinfo/python-list

Re: Looking For Geodetic Python Software
Howard Butler http://hobu.biz/ has some nice Python wrappers for gdal and Frank Warmerdam's other tools. I have to say, though, that geodesy is inherently complicated. Python makes it easy to program, but not easy to understand. http://maps.hobu.net:7080/RPC2 is an XMLRPC service that he exposes that will transform various coordinate systems: take a look at http://hobu.biz/index_html/projection_service/blogentry_view to see what I mean. Ron Phillips Tim Daneliuk wrote: Is anyone aware of freely available Python modules that can do any of the following tasks: 1) Given the latitude/longitude of two locations, compute the distance between them. Distance in this case would be either the straight-line flying distance, or the actual over-ground distance that accounts for the earth's curvature. 2) Given n latitude/longitude coordinates, compute the geocenter. That is, return the lat/long of the location that is most central to all n initial coordinates. 3) Given n lat/long coordinates, compute a Kruskal-type spanning tree. 4) Given n lat/long coordinates, compute an optimal (shortest or longest) visitation path that reaches each node exactly once. Better still would be something that had pluggable heuristic engines so we could try different approaches like greedy, shortest-path, hill climbing, and so forth. It would be even nicer if one could also simulate different routing schemes (Monte Carlo?). In effect, I'm looking for something that mates traditional graph traversal heuristics with operations research tools working on a geodetic coordinate system.
