Binary numpy array to list of integers?

by

@SteveTjoa’s answer is fine, but for kicks, here’s a numpy one-liner:

In [19]: a
Out[19]: 
array([[1, 1, 0, 0],
       [0, 1, 0, 0],
       [0, 1, 1, 1],
       [1, 1, 1, 1]])

In [20]: a.dot(1 << arange(a.shape[-1] - 1, -1, -1))
Out[20]: array([12,  4,  7, 15])

(arange is numpy.arange.)

If the bits are in the opposite order, change the order of the values produced by arange:

In [25]: a.dot(1 << arange(a.shape[-1]))
Out[25]: array([ 3,  2, 14, 15])
