I think this is going to be one of those simple-when-you-see-it problems, but it has got me baffled. [STOP PRESS: I was right. Solution was found. See the answers.] I am using Python's unittest framework to test a multi-threaded app. Nice and straight forward - I have 5 or so worker threads monitoring a common queue, and a single produ...
I am writing a binding system that exposes classes and functions to python in a slightly unusual way. Normally one would create a python type and provide a list of functions that represent the methods of that type, and then allow python to use its generic tp_getattro function to select the right one. For reasons I wont go into here, I ca...
I set up an ordering='ordering_number' Meta attribute to my Django model, thinking that Django will use it when comparing instances. (ordering_number is an IntegerField in my model.) For example, if I have an instance a with ordering_number = 4 and an instance b with ordering_number = 7, I'd expect that a < b would be True. However, I t...
I added some models in my models.py and I want to add an admin class to use a wysiwyg-editor in text-fields. Well, I know that Django itself doesn't support migrations and I've used South, but it doesn't work either. South doesn't "see" the change. Could...

I am about at wits end with what should be an extremely simple issue. Here is the format of a simple example that I wrote to try to fix my problem. I have a folder top with __all__ = ["p1","p2"] in __init__.py . I then have sub-folders p1 and p2 with __init__.py in both of them with __all__ again defined with the names of two simple modu...
I'm looking for a wrapper around cron. I've stumbled upon PyCron but it's a Python implementation, not a wrapper. Do you know any good cron Python wrapper ? If not, did you test PyCron, and what can you tell about it ? //EDIT (As an answer to comment asking for more details): I am looking for something to set a cron job in a pythoni...
I'm trying to serialize a list of python objects with JSON (using simplejson) and am getting the error that the object "is not JSON serializable". The class is a simple class having fields that are only integers, strings, and floats, and inherits similar fields from one parent superclass, e.g.: class ParentClass: def __init__(self, ...
Hi, I made simple python program to generate big text file: import sys import random f = open('data.txt', 'w') for i in range(100000000): f.write(str(i) + "\t" + str(random.randint(0,1000)) + "\n") f.close() When I launch it using CPython it eat all available OS memory and write nothing to the file. When I launch it on Jyth...

Pylint say W: 6: Using possibly undefined loop variable 'n' with this code: iterator = (i*i for i in range(100) if i % 3 == 0) for n, i in enumerate(iterator): do_something(i) print n because if the iterator is empty (for example []) n is undefined, ok. But I like this trick. How to use it in a safe way? I think that usin...
