Hi, I have an existing sqlite3 db file, on which I need to make some extensive calculations. Doing the calculations from the file is painfully slow, and as the file is not large (~10 MB), so there should be no problem to load it into memory. Is there a Pythonic way to load the existing file into memory in order to speed up the calculat...

So I declare a JFrame, and then try to add a panel, some text fields, all that good stuff. I get this error when I run it, however. "'NoneType' object has no attribute 'add'" Here's the basic cod...
For all my data in the GAE Datastore I have a model for keeping track of counters/total number of records (since we can't use traditional SUM queries). I want to know the most efficient way of incrementing these global count values whenever I insert/delete a record. This is what I'm currently doing: counter = DBCounter.all().fetch(1) db...
When doing quick scripts I like to use DocTests to make things a bit quicker, recently I saw someone using autospec at a recent DevCon I attended when they were introducing us to the concept of CodeKata. I spent the train ride home looking for a Python equivalent of Autospec & found modipyd, but I'm struggling to get it to run my doctes...
