The title asks it all. The content on the site I'm building wont change very quickly at all and so Memcache could potentially store data for months except for when I put up an update. Is there a way to make it clear the cache every time I deploy the site? I'm using the Python runtime. Update 1 Using jldupont's answer I put the followin...
I'm trying to build a level editor for a game I'm working on. It pulls data from a flat file and then based on a byte-by-byte search it'll assemble a grid from pre-set tiles. This part of the app I should have no issues with. The problem is that my test version of the editor which just loads a 16x16 grid of test tiles from 00 to FF is lo...
I have a grid (6 rows, 5 columns): grid = [ [None, None, None, None, None], [None, None, None, None, None], [None, None, None, None, None], [None, None, None, None, None], [None, None, None, None, None], [None, None, None, None, None], ] I augment the grid and it might turn into ...
I have been learning Python by following some pygame tutorials. Therein I found extensive use of the keyword self, and coming from a primarily Java background, I find that I keep forgetting to type self. For example, instead of self.rect.centerx I would type rect.centerx, because, to me, rect is already a member variable of the class. ...
I have an instance of SimpleHTTPServer, however when I try to call "shutdown" on it and there is a request handler that is blocked - the whole process will block. It does so even if I run the "serve_forever" method in a deamon thread. See example code at http://codepad.org/cn8EYdfg Any advice? ...

Hi, I have a python application which I cant edit its a black box from my point of view. The python application knows how to process text and return processed text. I have another application written in Java which knows how to collect non processed texts. Current state, the python app works in batch mode every x minutes. I want to make...
Following this question which asks (and answers) how to read .mat files that were created in Matlab using Scipy, I want to know how to access the fields in the imported structs. I have a file in Matlab from which I can import a struct: >> load bla % imports a struct called G >> G G = Inp: [40x40x2016 uint8] Tgt: [8...
Is there any solution to force the RawConfigParser.write() method to export the config file with an alphabetical sort? Even if the original/loaded config file is sorted, the module mixes the section and the options into the sections arbitrarily, and is really annoying to edit manually a huge unsorted config file. PD: I'm using python 2...
May i know how to find the cross product of 2 different vectors without the use of programming libraries? E.g given vector a = (1, 2, 3) vector b = (4, 5, 6) ...
I have a python based application which works like a feed aggregator and needs to be part of init.d script so that I could control the execution with start/stop/restart options. Also I want the init.d script to be setup as a cron job (I have example here). I found one sample here http://homepage.hispeed.ch/py430/python/daemon (PS. I ...
I've been a Perl guy for over 10 years but a friend convinced me to try Python and told me how much faster it is than Perl. So just for kicks I ported an app I wrote in Perl to Python and found that it runs about 3x slower. Initially my friend told me that I must have done it wrong, so I rewrote and refactored until I could rewrite and r...

Hello, I'm writing a Python module that wraps out a certain web service API. It's all REST, so relatively straightforward to implement. However, I found a problem when it comes to unit testing: as I don't run the services I made this module for, I don't want to hammer them, but at the same time, I need to retrieve data to run my tests...
Hi, all.I want to find a 3D plane equation given 3 points.I have got the normal calculated after applying the cross product. But the equation of a plane is known to be the normal multiply by another vector which what i am taught to be as P.OP. I substitute my main reference point as OP and i want P to be in (x, y, z) form. So that i can ...
I am trying to get a conceptual understanding of the nature of Python functions and methods. I get that functions are actually objects, with a method that is called when the function is executed. But is that function-object method actually another function? For example: def fred(): pass If I look at dir(fred), I see it has an att...
