Question

尝试用迭代值填充3D数组，但是只要循环结束，这些值似乎就会丢失。当我具有指定数组位置的值

dctArray[dctRow][dctColumn]

我尝试将其等同于3D阵列

dctArrayBlocks[i][dctRow][dctColumn] = dctArray[dctRow][dctColumn]

这很好，当我打印出来时，它很好并且具有正确的值（dctArrayBlocks [0] [0] [0]为1205）。但是，当我尝试打印整个数组时，这是不正确的。在这里：

不确定为什么我尝试在数组中打印单个值时是正确的，但是当我打印整个数组时，值不正确。这是完整的代码，感谢您的帮助！

    dctArray = np.zeros(shape = (8,8))

    Cu = 0.0
    Cv = 0.0

    dctArrayBlocks = np.zeros(shape = (4,8,8))

    for i in range(4):

        for dctRow in range(blockSize):

            for dctColumn in range (blockSize):

                dctSum = 0

                for row in range (blockSize):

                    for column in range (blockSize):

                        dctSum = dctSum + blocksList[i][row][column]*math.cos(((2.0*row+1)*dctRow*math.pi)/16.0)*math.cos(((2.0*column+1)*dctColumn*math.pi)/16.0)

                if(dctRow == 1):
                    cRow = 1/math.sqrt(2)

                else:
                    cRow = 1

                if(dctColumn == 1):
                    cColumn= 1/math.sqrt(2)

                else:
                    cColumn = 1

                dctArray[dctRow][dctColumn] = 1/4.0*cRow*cColumn*dctSum
                dctArrayBlocks[i][dctRow][dctColumn] = dctArray[dctRow][dctColumn]
                print(dctArrayBlocks[i][dctRow][dctColumn])
                #print(dctArrayBlocks)

        print(dctArrayBlocks[i])

Python值未正确附加到3D数组
