Following the example in PyUnit, I came up with the following unittest code that works fine. import unittest class Board: def __init__(self, x, y): self.x = x; self.y = y; def __eq__(self, other): return self.x == other.x and self.y == other.y class BoardTest(unittest.TestCase): def setUp(self): self.b10_10 ...
I have decided to learn how multi-threading is done in Python, and I did a comparison to see what kind of performance gain I would get on a dual-core CPU. I found that my simple multi-threaded code actually runs slower than the sequential equivalent, and I cant figure out why. The test I contrived was to generate a large list of random ...

I'm trying to use TF-IDF to sort documents into categories. I've calculated the tf_idf for some documents, but now when I try to calculate the Cosine Similarity between two of these documents I get a traceback saying: #len(u)==201, len(v)==246 cosine_distance(u, v) ValueError: objects are not aligned #this works though: cosine_distan...

Should I care about locality of entities on the Google App Engine datastore? Should I use custom entity key names for that? For example, I could use "$article_uuid,$comment_id" as the key name of a Comment entity. Will it improve the speed of fetching all comments for an article? Or is it better to use shorter keys? Is it a good practi...
Hello! Today, as I tried to put together a script in Octave, I thought, this may be easier in python. Indeed the math operators of lists are a breeze, but loading in the file in the format is not as easy. Then I thought, it probably is, I am just not familiar with the module to do it! So, I have a typical data file with four columns ...
I'm working with a product that has a built-in Jython 2.2 instance. It comes with none of the Python standard libraries. When I run this instance of Jython, the default path is ['./run/Jython/Lib', './run/Jython', '__classpath__'] I added all of the .py module files from Python 2.2 to the ./run/Jython/Lib directory, and I am able t...

I need to invoke make (build a makefile) in a directory different from the one I'm in, from inside a Python script. If I simply do: build_ret = subprocess.Popen("../dir1/dir2/dir3/make", shell = True, stdout = subprocess.PIPE) I get the following: /bin/sh: ../dir1/dir2/dir3/make: No such file or directory I've tr...

I'm having deadlock problems with this piece of code: def _entropy_split_parallel(data_train, answers_train, weights): CPUS = 1 #multiprocessing.cpu_count() NUMBER_TASKS = len(data_train[0]) processes = [] multi_list = zip(data_train, answers_train, weights) task_queue = multiprocessing.Queue() done_queue = mu...
I use several ad networks for my sites, and to see how much money I made I need to log in to each daily to add up the values. I was thinking of making a Python script that would do this for me to get a quick total. I know I need to do a POST request to log in, then store the cookies that I get back and then GET request the report page wh...

Looking around for python implementations of tries just so that I can understand what they are and how they work, I came across Justin Peel's patricia trie and found it very instructive: it's straightforward enough for one as new as I am to play around with it and learn from it. However there's something I think I'm not understanding: ...
I have some data either in list contains lists, or list contains tuples. data = [[1,2,3], [4,5,6], [7,8,9]] data = [(1,2,3), (4,5,6), (7,8,9)] And I want to sort by the 2nd element in the subset. Meaning, sorting by 2,5,8 where 2 is from (1,2,3), 5 is from (4,5,6). What is the common way to do this? Should I store tuples or lists in m...
I'm drawing a bunch of lines with the Python Imaging Library's ImageDraw.line(), but they look horrid since I can't find a way to anti-alias them. How can I anti-alias lines in PIL? If PIL can't do it, is there another Python image manipulation library that can? ...
For input file separate by space/tab like: 1 2 3 4 5 6 7 8 9 How to read the line and split the integers, then save into either lists or tuples? Thanks. data = [[1,2,3], [4,5,6], [7,8,9]] data = [(1,2,3), (4,5,6), (7,8,9)] ...
