For the new computer science assignment we are to implement a list/array using an inorder binary tree. I would just like a suggestion rather than a solution. The idea is having a binary tree that has its nodes accessible via indexes, e.g. t = ListTree() t.insert(2,0) # 1st argument is the value, 2nd the index to insert at t.get(0) # ...

Could anyone care to explain what this is or point me to documentation I am overlooking? Thanks. ...

Hi, I'm subclassing dict, but ran into a problem with setitem where one assignment works, but another assignment does not. I've boiled it down to the following basic problem: class CustomDict(dict): def __setitem__(self, key, value): super(CustomDict, self).__setitem__(key, value) Test 1 fails: data = {"message":"foo"} CustomDict(...

I've been trying to design a Google AppEngine Python handler regex and haven't been too successful in getting it to work. I'm trying to handle API calls similar to OpenStreetMap's. My current regex looks like this: /api/0.6/(.*?)/(.*?)\/?(.*?) But when this comes in: /api/0.6/changeset/723/close It incorrectly groups 723/close and ...
Ok, so here's the setup. In OS X (>= 10.5), is it possible, given a mounted usb device with a known location, say /Volumes/FLASHDRIVE, to find out whether this device is connecting through another usb device (a card reader for example) and if so, which one. Ideally, this could all be done in python, but if not that's ok too. ...
