I have problems opening a berkeley db in python using bdtables. As bdtables is used by the library I am using to access the database, I need it to work. The problem seems to be that the db environment I am trying to open (I got a copy of the database to open), is version 4.4 while libdb is version 4.6. I get the following error using bs...
Since Python is a dynamic, interpreted language you don't have to compile your code before running it. Hence, it's very easy to simply write your code, run it, see what problems occur, and fix them. Using hotkeys or macros can make this incredibly quick. So, because it's so easy to immediately see the output of your program and any erro...
According to the feedparser documentation, I can turn an RSS feed into a parsed object like this: import feedparser d = feedparser.parse('http://feedparser.org/docs/examples/atom10.xml') but I can't find anything showing how to go the other way; I'd like to be able do manipulate 'd' and then output the result as XML: print d.toXML() ...

I love Python because it comes batteries included, and I use built-in functions, a lot, to do the dirty job for me. I have always been using happily the os.path module to deal with file path but recently I ended up with unexpected results on Python 2.5 under Ubuntu linux, while dealing with string that represent windows file paths : fi...

Still 'diving in' to Python, and want to make sure I'm not overlooking something. I wrote a script that extracts files from several zip files, and saves the extracted files together in one directory. To prevent duplicate filenames from being over-written, I wrote this little function - and I'm just wondering if there is a better way to d...

I've been doing CMS sites for clients using Joomla for a while now, but I've been migrating a lot of my coding over to Python and have been looking for a good CMS solution that's written in Python. Most of what I've seen so far is either Zope based (Plone) or Django based. I'm not totally opposed to something written in a Python framewo...
