数组拼接方法一 思路:首先将数组转成列表,然后利用列表的拼接函数 、`extend()`等进行拼接处理,最后将列表转成数组。 示例1: [1, 2, 5, 10, 12, 15] array([ 1, 2, 5, 10, 12, 15]) 该方法只适用于简单的一维数组拼接,由于转换过程很耗时间,对于
To concatenate 2D arrays with 1D array in NumPy, we have different approaches, we can use ravel() to flatten the 2D array and then we can use concatenate so that the result would be a 1D array with all the elements of both the array together. Secondly, we can use the column_stack()...
