Accepting request 241241 from devel:languages:python

I intend to submit python-pandas to openSUSE:Factory.  python-pandas is a tool that makes it easy to do complex data import, export, and manipulation.  It has become one of the critical tools for data analysis in python, like python-numpy, python-scipy, python-matplotlib, and IPython (all of which are in openSUSE:Factory).

This is a dependency of python-pandas.

This package is also useful on its own for greatly increasing the speed of python-numpy operations.  (I know I said the same thing about python-Bottleneck, both accelerate different types of numpy operations in different ways, that is why they are both used here).

+%description
+Numexpr is a fast numerical expression evaluator for NumPy.  With it,
+expressions that operate on arrays (like "3*a+4*b") are accelerated
+and use less memory than doing the same calculation in Python.
