How can I quickly extract two rows of a scipy.sparse.lil_matrix and apply bitwise operations on them? I've tried:

np.bitwise_and(A[1,:], A[2,:])

but NumPy seems to want an array type according to the documentation.

How do you construct an array suitable for numpy sorting?

I need to sort two arrays simultaneously, or rather I need to sort one of the arrays and bring the corresponding element of its associated array with it as I sort. That is if the array is [(5, 33), (4, 44), (3, 55)] and I sort by the first axis (labeled below dtype='alpha') then I want: [(3.0, 55… >>> More

Compound assignment operators in Python's Numpy library

as seen on Programmers - Search for 'Programmers'
The "vectorizing" of fancy indexing by Python's numpy library sometimes gives unexpected results. For example: import numpy a = numpy.zeros((1000,4), dtype='uint32') b = numpy.zeros((1000,4), dtype='uint32') i = numpy.random.random_integers(0,999,1000) j = numpy.random.random_integers(0,3,1000) a[i… >>> More
