By the way, here's my work in progress: https://gist.github.com/johndoe31415/7e432b4f47f0030f0903dbd6a401e5dc I really really love the look & feel, but am unsure if there's a better way for this? Cheers, Joe -- >> Wo hattest Du das Beben nochmal GENAU vorhergesagt? > Zumindest nicht öffentlich

Brainstorming on recursive class definitions

Hi group, so I'm having a problem that I'd like to solve *nicely*. I know plenty of ways to solve it, but am curious if there's a solution that allows me to write the solution in a way that is most comfortable for the user. I'm trying to map registers of a processor. So assume you have a n bit ad

Hi all. I thought I had a pretty good grasp of Python's scoping rules, but today I noticed something that I don't understand. Can anyone explain to me why this happens? >>> x = 'global' >>> def f1(): x = 'local' class C: y = x return C.y >>> def f2(): x = 'local' cl

Generating class definitions at runtime in memory from XSD or JSON

Does anyone know of a library to generate class definitions in memory, at runtime, from XSD or JSON? I know about PyXB, generateDS and some others, but they all rely on generating python source files at the command line, and then using those to parse XML. Thanks -- http://mail.python.org/mailman

Amateur question on class definitions...

So I am defining my Python classes for a Django data model. I have a the following class hierarchy and would value some expert input on how to best implement this. I have many instances of a particular class which I call a "workflow", e.g. wf_1, wf_2, wf_3, etc. These class instances of workflows

Dynamically Update Class Definitions?

Is there a way to loop through all instantiated objects and update their classes when a source file changes? I know about Michael Hudson's method (http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/160164), but you have to modify all your classes to subclass AutoReloader. Is there something le
