I am interested in learning Python and Django. Are there any books that you would recommend especially to Java / JavaEE developers? I already know Dive into Python (by Mark Pilgrim) and the Book of Django (although I think the latter expects readers to already know Python). Cheers! ...
I'm trying to get a PUT request from Python into a servlet in Tomcat. The parameters are missing when I get into Tomcat. The same code is happily working for POST requests, but not for PUT. Here's the client: lConnection = httplib.HTTPConnection('localhost:8080') lHeaders = {"Content-type": "application/x-www-form-urlencoded", ...
Hey! Is it possible to make python run on your homepage? I know, this is a really stupid question but please don't pick on me for my stupidity :) If it is possible, how? Do you have to upload/install the executing part of Python to you website using FTP? or...? Edit: Just found out my provider does not support python and that shell ac...
I'm looking into way to track events in a django application (events would generally be clicks tied to a specific unique user id). These events would essentially contain an event type like "click" and then each click event would be assigned to a unique id (many events can go to one id) and each event would have a data set including item...
Thanks to those who've answered my previous questions and gotten me this far. I have a table of about 25,000 vectors, each with 48 dimensions, with values ranging from 0-255. I am attempting to develop a Locality Sensitive Hash (http://en.wikipedia.org/wiki/Locality-sensitive_hashing) algorithm for finding a near neighbor or closest ne...
I'm really quite frustrated at this point. I have an existing hg repository that has months of coding history in it, and I want to get this into a private Github repository so I can work on it from there. Unfortunately I use Windows and I can't seem to find any way to convert the repository that I can actually get to work properly. Pract...

Due to the nature of my application, I need to support fast inserts of large volumes of data into the database. Using executemany() increases performance, but there's a caveat. For example, MySQL has a configuration parameter called max_allowed_packet, and if the total size of my insert queries exceeds its value, MySQL throws an error. ...

Is there an elegant way to do this: def convert_val(val): do a series of things to each value, whether list or single val return answer or list of...

More and more libraries are being ported to Python 3, and I suspect the changes will happen more and more rapidly as time goes on. However, as a non-newbie to Python, there are quite a few 3rd party libraries I use (matplotlib, pygame, pyGTK, Tkinter, among others). I know I should just be able to go to their site(s) to find out if they ...

When I update my objectListView list it flickers/flashes white, is this normal behaviour or can it be prevented. The list gets updated around every 1-5 seconds using the AddObject method if that makes any difference. ...
I'm working on some software that consists of a server and clients on one machine that communicate via local sockets. The server (written in Java) opens a java.net.ServerSocket on port 9000, and the clients (in either Java or Python) have to connect to localhost:9000 to communicate. In Windows and Linux, this works fine. On Mac OS X (...
Why does this code eat up memory? When I run it it slowly consumes more memory with every loop, and I have something like 300000 loops. I'm using Windows, and Python 2.6. def LoadVotes(self): old_votes=Votes.objects.all() amount=old_votes.count() print 'Amount of votes is: ' + str(amount) c=0 for row in old_votes: ...
Okay, so the answer is probably obvious, but I don't know the correct way to get the program to respond differently depending on what the user types. octopusList = {"first": ["red", "white"], "second": ["green", "blue", "red"], "third": ["green", "blue", "red"]} squidList = ["first", "second", "third"] squid = r...
I have a RegEx for validating email addresses, but I'm really looking to validate a whole From header. Any of these would be valid: [email protected] <[email protected]> My Name <[email protected]> Is there anything out there that would validate these as valid from headers? I'm going to look in the smtp library :) ...
I'm having an issue with a rather intricate interaction of C++ and Python that I'm hoping the community can help me with. If my explanation doesn't make sense, let me know in the comments and I'll try to clarify. Our C++ code base contains a parent classes called "IODevice" which is a parent to other classes such as "File" and "Socket"...
