There is a new package called DimPy which can create multi-dimensional arrays in python very easily. To install use pip install dimpy. Usage example: from dimpy import * a=dim(4,5,6) # This is a 3 dimensional array of 4x5x6 elements. Use any number of dimensions within '( ) ' sepa...
I have been trying to perform a simple operation, but I can't seem to find a simple way to do it using Numpy functions without creating unnecessary copies of the array. Suppose we have the following 3-dimensional array : In [171]: x = np.arange(24).reshape((4,3,2)) In [172]: ...
NumPy: N-dimensional array - An ndarray is a (usually fixed-size) multidimensional container of items of the same type and size. The number of dimensions and items in an array is defined by its shape, which is a tuple of N positive integers that specify
Example A 2-dimensional array of size 2 x 3, composed of 4-byte integer elements: >>>x=np.array([[ 1,2,3],[4,5,6]],np.int32)>>>type(x)<type 'numpy.ndarray'>>>x.shape( 2, 3)>>>x.dtypedtype('int32') The array can be indexed using Python container-like syntax: >>>x...

numpy.random.shuffle(x)Modify a sequence in-place by shuffling its contents. This function only shuffles the array along the first axis of a multi-dimensional array. The order of sub-arrays is changed but their contents remains the same. ...
