I have Python 2.6 and I want to install easy _ install module. The problem is that the only available installation package of easy _ install for Python 2.6 is an .egg file! What should I do? ...
I'm using Python and Qt 4.4 and I have to print some pages. Initially I thought I'd use HTML with CSS to produce those pages. But HTML has some limitations. Now the question is: is there anything that's better than HTML but just (or almost) as easy to use? Additionally, it should be GPL-compatible. Edit: kdgregory & Mark G: The most o...
I want to create a zip file. Add a folder to the zip file and then add a bunch of files to that folder. So I want to end up with a zip file with a single folder with files in. I dont know if its bad practice to have folders in zip files or something but google gives me nothing on the subject. I started out with this: def addFolderTo...
Hey everyone, Is there a standard way to associate version string with a python package in such way that I could do the following? import foo print foo.version I would imagine there's some way to retrieve that data without any extra hardcoding, since minor/major strings are specified in setup.py already. Alternative solution that I f...
I'm coding the menu for an application I'm writing in python, using wxPython libraries for the user interface, and I'm attempting to add icons to some of the menu items. Because I'm trying to be conscientious about it, I'm trying to limit the damage done if one of the image files referenced doesn't exist, and the most simple method (in ...
My little brother is just getting into programming, and for his Science Fair project, he's doing a simulation of a flock of birds in the sky. He's gotten most of his code written, and it works nicely, but the birds need to move every moment. Tkinter, however, hogs the time for its own event loop, and so his code won't run. Doing root.ma...
Hi all, I'm using the SQLAlchemy Python ORM in a Pylons project. I have a class "Project" which has a one to many relationship with another class "Entry". I want to do a query in SQLAlchemy that gives me all of the projects which have one or more entries associated with them. At the moment I'm doing: [project for project in Session.que...
I was having trouble parsing some dodgy HTML with BeautifulSoup. Turns out that the HTMLParser used in newer versions is less tolerant than the SGMLParser used previously. Does BeautifulSoup have some kind of debug mode? I'm trying to figure out how to stop it borking on some nasty HTML I'm loading from a crabby website: <HTML> <...
I'm writing a little web app with webpy, and I'm wondering if anyone has any information on a little problem I'm having. I've written a little ORM system, and it seems to be working pretty well. Ideally I'd like to stitch it in with webpy, but it appears that just using it as is causes thread issues (DB connection is instantiated/access...
I'm coming to learn Perl from a Python background where the following hash-to-string conversion is built in to the language: >>> d = {'a': 1, 'b': 2, 'c': 3} >>> str(d) "{'a': 1, 'c': 3, 'b': 2}" Is there a builtin and/or module that has a subroutine with output along the lines of: "('a' => 1, 'b' => 2, 'c' => 3)" Strangely, a web ...
Hello, I need to be able to modify every single link in an HTML document. I know that I need to use the SoupStrainer but I'm not 100% positive on how to implement it. If someone could direct me to a good resource or provide a code example, it'd be very much appreciated. Thanks. ...
I have a "manager" process on a node, and several worker processes. The manager is the actual server who holds all of the connections to the clients. The manager accepts all incoming packets and puts them into a queue, and then the worker processes pull the packets out of the queue, process them, and generate a result. They send the resu...
Hello, In Twisted when implementing the dataReceived method, there doesn't seem to be any examples which refer to packets being fragmented. In every other language this is something you manually implement, so I was just wondering if this is done for you in twisted already or what? If so, do I need to prefix my packets with a length head...
Given this input: [1,2,3,4] I'd like to generate the set of spanning sets: [1] [2] [3] [4] [1] [2] [3,4] [1] [2,3] [4] [1] [3] [2,4] [1,2] [3] [4] [1,3] [2] [4] [1,4] [2] [3] [1,2] [3,4] [1,3] [2,4] [1,4] [2,3] [1,2,3] [4] [1,2,4] [3] [1,3,4] [2] [2,3,4] [1] [1,2,3,4] Every set has all the elements of the original set, permuted to ap...
Consider the following code: def CalcSomething(a): if CalcSomething._cache.has_key(a): return CalcSomething._cache[a] CalcSomething._cache[a] = ReallyCalc(a) return CalcSomething._cache[a] CalcSomething._cache = { } This is the easiest way I can think of for simulating a 'local static' variable in python. What bo...
Hi, Has anyone had any success with getting data via Xml-rpc using Python or Perl...? I'm using the continuum.py library: #!/usr/bin/env python from continuum import * c = Continuum( "http://localhost:8080/continuum/xmlrpc" ) or: #!/usr/bin/perl use Frontier::Client; my $url = "http://dev.server.com:8080/continuum/xmlrpc"; my ...
Can you give me some links or explain how to configure an existing python project onto Netbeans? I'm trying it these days and it continues to crash also code navigation doesn't work well and I've problems with debugging. Surely these problems are related to my low eperience about python and I need support also in trivial things as organ...
Hi all, What is the best way to sniff network packets using Python? I've heard from several places that the best module for this is a module called Scapy, unfortunately, it makes python.exe crash on my system. I would assume that it's just a problem with how I installed it, except that many other people have told me that it doesn't wor...
I am adding some wx.StaticText objects on top of my main wx.Frame, which already has a background image applied. However, the StaticText always seems to draw with a solid (opaque) background color, hiding the image. I have tried creating a wx.Color object and changing the alpha value there, but that yields no results. Is there any way I ...
I was browsing through "Text Processing in Python" and tried its example about Schwartzian sort. I used following structure for sample data which also contains empty lines. I sorted this data by fifth column: 383230 -49 -78 1 100034 '06 text' 9562 'text' 720 'text' 867 335067 -152 -18 3 100030 'text' 2400 'text' 2342 'text' 696 136592 ...
