Re: [Numpy-discussion] rant against from numpy import * / from pylab import *

Sebastian, I am trying to move things in the direction of simpler and cleaner namespaces, but I think that to do it well requires a systematic approach to the continuing numpification of mpl, so I have been working on mlab.py before tackling pylab. I hope everything can be done via reorganiza

[Numpy-discussion] Where to put misc C function in numpy ?

Hi, Following the thread on facilities for SIMD friendly allocations, I have a basic private branch ready for review, but I have one problem: where to put the allocation functions ? The problem is the following: data buffers are allocated/deallocated with functions defined in ndarrayobject,h PyMe

Hi all, I have a list e.g. >>> bounds [(1950.0, 2100.0), (1800.0, 1850.0), (1600.0, 1630.0), (1400.0, 1420.0), (1200.0, 1210.0), (990, 1018.0), (10, 12), (12.0, 14.0), (14.0, 16.0), (16.0, 18.0), (18.0, 20)] How can I extract the first value of each pair given in parenthesis i.e. 1950,1800,1600,1
