- NumPy Creating Arrays - W3Schools
Create a 3-D array with two 2-D arrays, both containing two arrays with the values 1,2,3 and 4,5,6: import numpy as np arr = np array([[[1, 2, 3], [4, 5, 6]], [[1, 2, 3], [4, 5, 6]]])

功能: 将数据转化为矩阵 a=[[1,2,3],[4,5,6],[7,8,9]] b=np array(a) c=np asarray(a) a[2]=1 print(a) print(b) print(c) 从中我们可以看出np array与np asarray功能是一样的,都是将输入转为矩阵格式。当输入是列表的时候,更改列表的值并不会影响转化为矩阵的值。

array ([[0, 1, 2], [3, 4, 5]]) Note that in order to use the reshape method, the original array must have the same number of elements as the array that you're trying to reshape it into If you're curious about the current shape of a NumPy array, you can determine its shape using NumPy's shape attribute
