What is PyQwt ( http://pyqwt.sourceforge.net ) ?
- it is a set of Python bindings for the Qwt C++ class library which
extends the Qt framework with widgets for scientific and engineering
applications. It provides a widget to plot 2-dimensional data and
various widgets to display and contro

Pyrex is a good bet too:

The advantage with pyrex is that you don't have to write any C at all.
You will have to use a compiler that is compatible with your Python buil

Hello all,
I just recently updated to the SVN version of numpy to test my code
against it, and found that a small change made to
numpy.get_printoptions (it now returns a dictionary instead of a
list) breaks my code.
Here's the changeset:

Hi,
I am writing a function that would take a list of datetime objects and
a list of single letter characters (such as ["A","B","C"]). The number
of items tend to be big and both the list and the numpy array have all
the functionalities I need.
Do you think I should use numpy arrays or the regula
