ndarray类型的数组array的形状是66则取最中间4个数据的代码是

array[1:5, 1:5]

假设ndarray类型的数组array为：

array([[1, 2, 3, 4, 5, 6],
       [7, 8, 9, 10, 11, 12],
       [13, 14, 15, 16, 17, 18],
       [19, 20, 21, 22, 23, 24],
       [25, 26, 27, 28, 29, 30],
       [31, 32, 33, 34, 35, 36]])

则上述代码将返回：

array([[ 8,  9, 10, 11],
       [14, 15, 16, 17],
       [20, 21, 22, 23],
       [26, 27, 28, 29]])
