As I understand it, Python (2.5.2) does not have real support for abstract classes. Why is pylint complaining about this class being an "Abstract class not reference?" Will it do this for any class that has NotImplementedError thrown? I have each class in its own file so if this is the case I guess I have no choice but to suppress this ...

I'm curious if anyone out there knows of something perhaps like Akismet, but where content doesn't have to go off to a 3rd party server. In a situation with critically sensitive data (patient records for instance) I wouldn't necessarily want that information sent off to another server I don't have control over. I really like Akismet, it ...

Hi, I am porting some Java code to Python and we would like to use Python 3 but I can't find LDAP module for Python 3 in Windows. This is forcing us to use 2.6 version and it is bothersome as rest of the code is already in 3.0 format. ...

After the thread has been created, I ask for some input on user with the following code: user_input = raw_input('>> ') So when the script it run the user receives the '>>' prompt, but when the logger from the created thread starts logging it starts to...
I have developed some applications in Google App Engine but sometimes I have problems to "translate" my rational database mind to datastore objects (most of the time because I don't want to use the Key as ID of the data.) So, if I populate a combo (or any other control) how can I distinguish the uniqueness of the data? Now I'm reading ...
I read through the tutorial on the cherrypy website, and I'm still having some trouble understanding how it can be implemented in a modular, scalable way. Could someone show me an example of how to have cherrypy receive a simple http post to its root, process the variable in some way, and respond dynamically using that data in the resp...

Are Python docstrings and comments stored in memory when module is loaded? I've wondered if this is true, because I usually document my code well; may this affect memory usage? Usually every Python object has a __doc__ method. Are those docstrings read from the file, or processed otherwise? I've done searches here in the forums, G...

Why would I want to use java portlets above tomcat and gwt? Would portlets make it less- or un- necessary for me to use jsp and jsf? Has Jboss been part of the portlet evolution culture? Does Jboss satisfy the portlet jsrs? What portlet implementation/brand would run on gae java and gae python? Are portlet specs due to peer pressure fro...
