Hi everyone,
There is currently a competition running that could help give Python in
computational science a bit of visibility. The competition is for the
most popular recently published article on the Scholarpedia website, one
of which is about a Python package "Brian" for computational

Hi all,
Has anyone managed to get any of the Python CUDA libraries working on
Windows using cygwin? Which one, and was anything special required?
Thanks in advance for any advice.

I also wrote a units package which I'm using for a project of my own
(a spiking neural network simulator package called 'Brian'), released
separately as a package called Piquant which you can get at
sourceforge:

Thanks for the replies, but it's not what I meant. What I want to be
able to determine is whether or not the user is running from an
interactive shell (like IPython or IDLE). Checking if
__name__=='__main__' checks if the current module is the one being
run, but suppose you have two modules A and B
Hi all,
Is there any standard way to tell if the user is running from a module
or from an interactive shell like IDLE or IPython? The best I've come
up with so far is for a function to look at

Hi all,
So I understand that properties belong to a class not an instance, but
nonetheless I want to add properties to an instance. I have a class
which when an instance is created runs some fairly complicated code
and produces a set of names which I'd like to be able to access via
properties. At
Hi all,
As I understand it, the idea behind duck typing is that you just take
an object and if it has the methods you want to use you use it
assuming it to be the right type of object. I'm interested in
extending this idea a bit, but I feel the sort of thing I have in mind
has already been thought
It's a bit cheap, but how about
>>> from inspect import getsource
>>> print getsource(getsource)
or similarly
def f(g):
import inspect
return inspect.getsource(g)
print f(f)

Well I tried the NumPy array thing that I was talking about, to
parallelise the problem, and there were some difficulties with it.
Firstly, the pruning makes a really big difference to the speed, and
you don't get that if you're trying to parallelise the problem because

Great solutions both of you! Much nicer than mine. I particularly like
Arnaud's latest one based on folding because it's so neat and
conceptually simple. For me, it's the closest so far to my goal of the
most elegant solution.
So anyone got an answer to which set of numbers give
Decided I may as well post my other solution while I'm at it. The neat
trick here is redefining the add, mul, etc. functions so that they
raise exceptions for example if x>y then add(x,y) raises an exception

Hi all,
It's great how many different sorts of solutions (or almost solutions)
this puzzle has generated. Speedwise, for reference my solution posted
above takes about 40 seconds on my 1.8GHz laptop, and the less elegant
version (on my webpage linked to in the original post) takes about 15
seconds
Hi Marek,
That's a really nice solution (and ultrafast).
Unfortunately I realise I stated the problem imprecisely. You're only
allowed to use each number once (otherwise there's a trivial solution
for every problem, i.e. x/x + x/x + x/x + ... + x/x repeated y times
for target y given any source n
Ever since I learnt to program I've always loved writing solvers for
the Countdown numbers game problem in different languages, and so now
I'm wondering what the most elegant solution in Python is.
If you don't know the game, it's simple: you're given six randomly
chosen positive integers, and a t
Hi Rüdiger,
Thanks for your message. I liked your approach and I've been trying
something along exactly these sorts of lines, but I have a few
problems and queries.
The first problem is that the id of the frame object can be re-used,

I had previously thought about the possibility of the classes keeping
track of their instances. I guess this could probably be done quite
transparently with a decorator too (as we have many different types of
objects being collected together). The only issue is th
Hi all,
I'm part of a small team writing a Python package for a scientific
computing project. The idea is to make it easy to use for relatively
inexperienced programmers. As part of that aim, we're using what we're
