I've seen many examples online and in this forum of how to create properties in Python with special getters and setters. However, I can't get the special getter and setter methods to execute, nor can I use the @property decorator to transform a property as readonly. I'm using Python 2.6.4 and here is my code. Different methods to use p...
As part of an automated test, I have a python script that needs to call two shell scripts that start two different servers that need to interact after the calling script ends. (It's actually a jython script, but I'm not sure that matters at this point.) What can I do to ensure that the servers stay up after the python script ends? At th...
Is there a way to declare which signals are subscribed by a Python application over DBus? In other words, is there a way to advertise through the "Introspectable" interface which signals are subscribed to. I use "D-Feet D-Bus debugger". E.g. Application subscribes to signal X (using the add_signal_receiver method on a bus object). ...
Hi all, In the example below: from PyQt4 import QtCore, QtGui class Ui_Dialog(QtGui.QDialog): def __init__(self,parent=None): QtGui.QDialog.__init__(self,parent) self.setObjectName("Dialog") self.resize(600, 500) self.model = QtGui.QDirModel() self.tree = QtGui.QTreeView() self.tree...
I am looking for Growl-like, Windows balloon-tip-like notifications library in Python. Imagine writing code like: >>> import desktopnotifier as dn >>> dn.notify('Title', 'Long description goes here') .. and that would notify with corresponding tooltips on Mac, Windows and Linux. Does such a library exist? If not, how would I go about ...
I'm wondering because CherryPy is, from my knowledge, built purely in Python, which is obviously slower than C et al. Does this mean that it's only good for dev / testing environments, or could I use it behind NGINX like I use Apache with Fast CGI currently? ...
Setup: I have the user object in hand, via win32com.client.Dispatch('ADsNameSpaces'), in a standard Windows environment, using ActiveState Python of the 2.6 flavor. Apparently, Get() and Put()/SetInfo() methods are the appropriate ways to read from and write to properties of the object. My approach has been to simply adapt examples fro...
The hashlib Python module provides the following hash algorithms constructors: md5(), sha1(), sha224(), sha256(), sha384(), and sha512(). Assuming I don't want to use md5, is there a big difference in using, say, sha1 instead of sha512? I want to use something like hashlib.shaXXX(hashString).hexdigest(), but as it's just for caching, I'...
Hi All, Just curious how people are deploying their Django projects in combination with virtualenv More specifically, how do you keep your production virtualenv's synched correctly with your development machine? I use git for scm but I don't have my virtualenv inside the git repo - should I, or is it best to use the pip freeze and t...

Hi Can anyone explain why example 1 below works, when the r prefix is not used? I thought the r prefix must be used whenever escape sequences are used? Example 2 and example 3 demonstrates this.. # example 1 import re print (re.sub('\s+', ' ', 'hello there there')) # prints 'hello there there' - not expected as r prefix is not...
I've been developing a Facebook app using Google App Engine in Python and the pyfacebook bindings. For weeks everything worked fine but suddenly it stopped. At first I thought it was a code change so I rolled back the entire dev directory to a version I knew worked, but still it failed. It's possible a change I made to the application'...

I would like to see the xml response. So basically I would like to send the following as my request to the server: <?xml version="1.0"?> <methodCall> <methodName>pr...
Is there a way to get nosetests --pdb to automatically show you the error you're trying to debug, as well as a backtrace, BEFORE dumping you into pdb? i.e. instead of: awagner@hesse:/home/awagner/optimization/illumination_search$ nosetests --pdb test_bool_rep (optimization.illumination_search.test_subset_search.SubsetSearchTest) ... ok ...
Say I do something like this in a python shell for my Django app: >>>from myapp.models import User >>>user = User.objects.get(pk=5) >>>groups = user.groups.all() What I'd like to do is stash these 3 commands somehow without leaving the shell. The goal being I can quickly restore a similar environment if I restart the shell session lat...
