What is the simplest way to implement a remote FIFO queue as a Python GAE application and then push/pull name-value pair dictionaries to and from it? For example, when an http get is made to the GAE application, the GAE app would return the oldest collection of name-value pairs that were posted to the app which have not been previously...

Suppose I have a class with a string instance attribute. Should I initialize this attribute with "" value, or None is OK either? def __init__(self, mystr = "") self.mystr = mystr or def __init__(self, mystr = None) self.mystr = mystr Thanks Edit: What I thought is that if I use "" as an initial value, I "declare" a variable ...
Hi, This might be a simple question, but i can't seem to grasp it. I have two simple models in models.py: Service and Host. Host.services has a m2m relationship with Service. In other words, a host has several services and one service can reside on multiple hosts; a basic m2m. models.py class Service(models.Model): servicena...

Since an assignment problem can be posed in the form of a single matrix, I am wandering if numpy has a function to solve such a matrix. So far I have found none. Maybe one of you guys know if numpy/scipy has an assignment-problem-solve function? Edit: In the meanwhile I have found a python (not numpy/scipy) implementation at http://www....
When developing in ActionScript 3, I often find myself looking for a way to achieve something similar to what is offered by python's __getattr__ / __setattr__ magic methods i.e. to be able to intercept attribute lookup on an instance, and do something custom. Is there some acceptable way to achieve this in ActionScript 3? In AS3 attrib...

I have recently started experimenting with Django for some web applications in my spare time. While designing the data model for one, I came across the dilemma of using inheritance to define a user of the website or using a technique known as monkey patching with the User class already supplied by the framework. I tried to add a field b...
Hi all: It's weird to me that the import fails even when it's in the sys.path. today, I set up a google app engine django environment on ubuntu in my lab's pc. And it works fine when I checked out the code and ran it in windows(same pc in the lab). But when I went to the dorm, and checked out the code and start to run, it failed weird...
I'm working on a program where I store some data in an integer and process it bitwise. For example, I might receive the number 48, which I will process bit-by-bit. In general the endianness of integers depends on the machine representation of integers, but does Python do anything to guarantee that the ints will always be little-endian?...
