Numpyoffers common operations which include concatenating regular 2D arrays row-wise or column-wise. We are also using theflatattribute to get a 1D iterator over the array in order to achieve our goal. However, this approach is relatively slow: importnumpy regular_list = [[1,2,3,4], [5,...
Original 2D array: [[1 2 3] [4 5 6]] Flattened array (row-major order): [1 2 3 4 5 6] Example 2Here in this example we show how a 3D array is flattened into a 1D array in column-major order which yields [1, 5, 3, 7, 2, 6, 4, 8] −Open Compiler import numpy as...

In the above code a 2D array y is defined with values [2, 3] and [4, 5]. The flatten() method is then called on y which returns a flattened 1D array. Therefore, the elements in the first row of y (2 and 3) come first in the flattened array, followed by the elements in the...
