Hi,
Before I start I want to admit that I don't understand much about

So here is a quote, I would like to know if this is "standard

Good afternoon,
The following works:
import pyodbc
import numpy as np
connection = pyodbc.connect('DSN=DSNname')
cursor = connection.cursor()
symbol = 'ibm'
request = "select to_days(Date), Close from price where symbol = '" +
symbol + "' and date > '2006-01-01'"
for row in cursor.execute(reques
Thanks Fernando,
Good idea. I'll apply your suggestion.

I've just committed a fix. I changed the [NPY_MAXDIMS] arrays to pointers (Pyrex
doesn't care, really) and changed the flatiter *items to void **items.

This strikes me as an excellent argument for including an n-d array in
the Python standard lib.
I can't imagine gtk-python is doing a lot of scientific number crunching

Until mpl drops support for the compatibility layers, you may want to
set up a simple pylab profile. In ~/.ipython make a file cal

sure is:
Numeric.asarray()
numpy.asarray()
Could it be any easier?

Hi There,
A few months ago, I posted the first release of pyaudio, a python
module to give numpy/scipy environment audio file IO capabilities (ala
matlab wavread and co). I recently took time to update it significantly,
and as several people showed interest in pyaudio recently, I thought

Hi Travis,
The vpython project was attempting to migrate to numpy and may have
achieved it, but I think there may have been some outstanding questions.
I'm not sure of the status, but, since you ask, I'd like to see vpython

Thanks Alan & Chris,
My apologies. I was trying ones(), zeros() and empty() in ipython 0.7.2

of ones(), zeros() and empty() and I had assumed these were

but that doesn't fit what I need: the myarray class Francesc introduced is
just an object, not
