From: mo reina on 3 Jul 2010 13:48 an anyone recommend a resource (book,tutorial,etc.) that focuses on application development in python? something similar to Practical Django Projects, but for stand alone applications instead of web apps (for now). i'm in a bit of a funny place, i have a decent/good grasp of python syntax and my logic isn't bad, but i have no clue on how to assemble an application, i seem to be stuck on writing scripts. i've looked at the source of a few projects but the flow is way over my head, i understand the syntax but not the logic, which is why i'm looking for a project-cenetered learning resource, instead of a reference or language-feature resource. also, it seems that a lot of app programming is 90% gui bindings, with very little actual code, or am i totally way off mark? i recently picked up the django practical projects book, and in a few days i re-wrote a website i did with django. i feel it was the book's project-centric approach that made this possible.

I think you are referring to GUI applications. There are plenty of GUI Libraries out there. One of my favorites is the Qt library by Nokia (former by Trolltech) for which you can get python bindings PyQt and PySide. http://doc.qt.nokia.com/4.7-snapshot/index.html http://www.riverbankcomputing.co.uk http://www.pyside.org You might want to read through the tutorials given in the documentation at the Nokia site and possibly take a look at the examples provided with, e.g. PyQt. I'm sure other will add in more valuable links and suggestions. Best regards Andre

If the app is a gui app and if logic is overly intermixed with gui stuff, I am sure it can seem like that. Many recommend the MVC model-view-controller model for app design. Even that can be confusing; to me it should be model-controller-view, even though that is harder to say. What are the data (values and objects) and how are they stored? What are the rules for manipulating the data and objects? And then, and only then, how to communicate with the user? > > i recently picked up the django practical projects book, and in a few > days i re-wrote a website i did with django. i feel it was the book's > project-centric approach that made this possible. Another issue is who controls the flow of interactions, the user or the code. For instance, a gui form used for input tends to direct the user along a linear path. The same form, used for edit, presents existing data and allows the user to pick and choose the fields to edit. This distinction, along with MVC ideas, is important for reading source code. I have mostly seen this issue discussed in game reviews and game design writing. In computer games, there is the same general difference between a linear obstacle course game and a world to be explored in whatever order one wants. (And there are some with both an explorable world *and* a (somewhat optional) linear main quest line.) I am not familiar with any general app design books, but I have seen game design articles and books that are on a par with writing about web design. There are other books on business apps. -- Terry Jan Reedy

Do you have a particular project in mind? Getting unstuck, I think, is about having a goal and then you'll begin to seek out what you need to make that happen (see below). > also, it seems that a lot of > app programming is 90% gui bindings, with very little actual code, or > am i totally way off mark? I'm sure it varies greatly depending on the application. Depending on the complexity of the GUI and how much care goes into it, that can be a lot of code (it seems to me). > i recently picked up the django practical projects book, and in a few > days i re-wrote a website i did with django. i feel it was the book's > project-centric approach that made this possible. I don't know of a book oriented that way (sounds like a good idea), but you might take a look at this video "learning path" from the ShowMeDo website: http://showmedo.com/learningpaths/14/view It is focused on GUI (desktop and web) application development. There is a super basic starter video in there about making a Python image viewer application. Then the video series about building emol seems very thorough (there are 35 videos!), though I haven't watched it yet. What I would suggest is that you first decide what you want to accomplish. Then research and pick a GUI framework first (Tkinter, wxPython, PyQT, PyGTK), then whatever other tools you'll need (database? drawing? math/science?), which will either be in the standard library or in a 3rd party library. Any of the research on what tools to use can be Googled with bountiful results, as those questions are asked a lot. Then just jump in. This will prompt you to learn in a directed way.

You should definitely check out Dabo. Several years ago we were looking for something in Python for developing desktop apps, and while there were several useful tools, there wasn't anything that integrated them together. That was our motivation for creating Dabo. We have a few screencasts to help you get acquainted with Dabo; I'd recommend these two to start: http://cdn.cloudfiles.mosso.com/c129431/dataenvironment1.html http://cdn.cloudfiles.mosso.com/c129432/dataenvironment1.html We also have a pretty comprehensive tutorial document, available at: http://dabodev.com/pycon_tutorial If you have any other questions, join our email discussion list and post them there. There are many helpful people there to answer your questions. http://leafe.com/mailman/listinfo/dabo-users -- Ed Leafe
