1.6.52. numpy.byte_bounds¶

numpy.byte_bounds(a)[source]¶

Returns pointers to the end-points of an array.

Parameters:	a : ndarray Input array. It must conform to the Python-side of the array interface.
Returns:	(low, high) : tuple of 2 integers The first integer is the first byte of the array, the second integer is just past the last byte of the array. If a is not contiguous it will not use every byte between the (low, high) values.

Examples

>>> I = np.eye(2, dtype='f'); I.dtype
dtype('float32')
>>> low, high = np.byte_bounds(I)
>>> high - low == I.size*I.itemsize
True
>>> I = np.eye(2, dtype='G'); I.dtype
dtype('complex192')
>>> low, high = np.byte_bounds(I)
>>> high - low == I.size*I.itemsize
True
