Hi, I have an object that holds lots of ids that are accessed statically. I want to split that up into another object which holds only those ids without the need of making modifications to the already existen code base. Take for example: class _CarType(object): DIESEL_CAR_ENGINE = 0 GAS_CAR_ENGINE = 1 # lots of these ids class ...

So how do you let a python class inherit from a java class using jcc ,and especially how do you write a custom pyluc...

This class represents a list, I can define/modify/code the Base and the Column class. There's a way to know the order in which I defined the attributes hp/names? For example I want to define a method that...
Hello, I'm using cherrypy to implement a web server and I use nose to run my unit tests. However, there is a lot of debug noise that nose catches and prints to stdout, even when I use the --nologcapture, particularly cherrypy's logging messages. That makes the testing output quite difficult to read. I've thought that: def setUp(self):...

Hi all, I'd like to save the commands for a breakpoint in a .pdbrc, something like: b 81 commands 1 pp foo.attr1 pp foo.attr2 end b 108 commands 2 pp bar.attr1 pp bar.attr2 end This would automate setting the environment for the debugging session. However, this does not work with 'python -m pdb script.py', because at the ...
I'm very new to Django, having never developed on it. I'm trying to develop a site which has functionality exposed only to authenticated users (typical enterprise thing: for this discussion, let's say it's a private blogging platform). The functionality I'm looking for is: Users can create a new blog. each user can belong to multip...

Following a tutorial (in portuguese) on compiling it ends up ok, but when I run the tests i receive only a crypt message: "Fatal Python error: Interpreter not initialized (version mismatch?)"

Hello. I'm on Mac OSX 10.5.8. I have followed Jacob Kaplan-Moss's article on setting up Django with Buildout: http://jacobian.org/writing/django-apps-with-buildout/ Finally, I have got this Buildout to work! ...but I'm now needing PIL and Postgres for a complete isolated Django development area. I've tried to modify my buildout.cfg with...
I'm using the KHTMLPart component from the PyKDE (in Python) library to download some webpages in the background and return sizes of certain elements in pixels. I don't really need any visual output from this script, indeed I will probably run it on a server without X installed. The problem is that when I tell my application to run conso...
I'm running into a paradigm problem here. I don't know whether I should store money as a Decimal(), or if I should store it as a string and convert it to a decimal myself. My reasoning is this: PayPal requires 2 decimal places, so if I have a product that is 49 dollars even, PayPal wants to see 49.00 come across the wire. Django's Decim...
I'm building a site for a client using django. It's been hosted on shared hosting and mod_wsgi can't be used. In the old year, I got it working using fcgi, but when I got back, it was broken. I have replaced the fcgi script with a simple hello world script: #!/usr/bin/python def myapp(environ, start_response): start_response('200 O...
How can I format a string like this "%01.2f" % pr"%01.2f" % some_number but using the str.format() style? I'm used to this: '{0} {1}'.format(somevalue1, somevalue2) Is there a way to use that function style vs the old % style, and still achieve this decimal formatting? ...
Every now and then I come across code like this: foo = Foo() ... if foo.bar is not None and foo.bar.baz == 42: shiny_happy(...) Which seems, well, unpythonic, to me. In Objective-C, you can send messages to nil and get nil as the answer. I've always thought that's quite handy. Of course it is possible to implement a Null pattern i...

Hi All, I'm looking for a Naive Bayesian Classifier for PHP, ideally something equivalent to the Reverend Bayes version written in Python. Does anyone know of such a library? Basically I need to be able to train it with a set of labels and words i.e. GOOD = okay, happy, fun; BAD = wrong, rubbish, awful etc and then pass it a string val...
