Convert 2d numpy array into list of lists [duplicate]
Solution 1:
You can simply cast the matrix to list with matrix.tolist(), proof:
>>> import numpy
>>> a = numpy.ones((2,4))
>>> a
array([[ 1., 1., 1., 1.],
[ 1., 1., 1., 1.]])
>>> a.tolist()
[[1.0, 1.0, 1.0, 1.0], [1.0, 1.0, 1.0, 1.0]]
>>> type(a.tolist())
<type 'list'>
>>> type(a.tolist()[0])
<type 'list'>
