In the above snippet of code, the statementres = [*list1, *list2]replaces the list1 and list2 with the items in the given order i.e. elements of list1 after elements of list2. This performs concatenation and results in the below output. Output: Concatenated list: [10, 11, 12, 13...
In this example,numpy.concatenate()takes a tuple or list of arrays as its first argument. We passed inarray1andarray2as a tuple to the function. The function then returns a new array that contains all elements fromarray1andarray2in the order they were input. Advantages of Using Numpy Concat...

横1. np.concatenate(list, axis=0) 将数据进行串接,这里主要是可以将列表进行x轴获得y轴的串接 参数说明:list表示需要串接的列表,axis=0,表示从上到下进行串接 2.np.hstack(list) 将列表进行横向排列 参数说明:list.append([1, 2]), list.append([3, 4]) np.hstack(list) , list等于[1, 2, ...
