2.2.3: Indexing NumPy Arrays 索引 NumPy 数组 NumPy arrays can also be indexed with other arrays or other sequence-like objects like lists. NumPy数组也可以与其他数组或其他类似于序列的对象(如列表)建立索引。 Let’s take a look at a few examples. 让我们来看几个例子。 I’m first going to ...

To intersect more than two arrays, use functools.reduce: >>> from functools import reduce >>> reduce(np.intersect1d, ([1, 3, 4, 3], [3, 1, 2, 1], [6, 3, 4, 2])) array([3]) To return the indices of the values common to the input arrays along with the intersected value...

Write a NumPy program to split a 4x4 array along the second axis into two sub-arrays using np.hsplit. Create a function that divides a 4x4 matrix into sections along the columns and returns the parts. Test splitting of a 4x4 array with specified index positions and verify that the sum of...
