Python code to copy NumPy array into part of another array# Import numpy import numpy as np # Creating two numpy arrays arr1 = np.array([[10, 20, 30],[1,2,3],[4,5,6]]) arr2 = np.zeros((6,6)) # Display original
在上面的示例中,使用 np.copy() 函数将给定的 Numpy 数组“ org_array ”复制到另一个数组“ copy_array ” 推荐:NumPy二元运算符 示例:使用np.copy()函数将给定的3-D数组复制到另一个数组 # importing Numpy package import numpy as np # Creating a 3-D numpy array using np.array() org_array = ...

An array can be copied to another array by using the “=” assignment operator. But this operator does not create a duplicate copy of the main array and just creates a reference of the original array. So, if any value is changed to the original array then it will change the value of ...
