A 4d numpy array is an array nested 4 layers deep, so at the top level it would look like this: [ # 1st level Array (Outer) [ # 2nd level Array [[1, 2], [3, 4]], # 3rd level arrays, containing 2 4th level arrays [[5, 6], [7, 8]] ], [ # 2nd Level array [[9, 10], [11, 12]], [[13, 14], [15, 16]] ] ]

Feb 27, 2023 · In this article, the creation and implementation of multidimensional arrays (2D, 3D as well as 4D arrays) have been covered along with examples in Python Programming language. To understand and implement multi-dimensional arrays in Python, the NumPy package is used.
