问题：如何编写程序以便逐行遍历列表并附加到列表中（将用于 K 最近邻预测）

列表：[0, 19.2, 20.3, 21.3, 23.5, 24.6, 25.2, 25.4, 26.2, 26.3, 26.4, 8655, 光]

Such that it will be in a list after convert to 2D Array 
List:[[0],
     [19.2],
     [20.3],
     [21.3],
     [26.4],
     [Light]]

You can use the below code.

l = [0, 19.2, 20.3, 21.3, 23.5, 24.6, 25.2, 25.4, 26.2, 26.3, 26.4, 8655, 'Light']

final_list=[]
for i in l:
    final_list.append([i])

If you want to iterate through a table which I'm presuming to be a list of lists, then use the below code.

l1 = [0, 19.2, 20.3, 21.3, 23.5, 24.6, 25.2, 25.4, 26.2, 26.3, 26.4, 8655, 'Light']
[26.2, 25.7, 25.2, 25.3, 22.3, 21.2, 20, 19.2, 19.1, 0, 0, 8655 , 'Light']
[0, 0, 54.2, 56.3, 62.3, 63.3, 65.2, 65.3, 65.3, 65.4, 65.4, 8483, 'Fan']
[65.4, 65.2, 65.1, 64.2, 63.2, 62.5, 61.3, 56.4, 53.8, 53.2, 0, 8483, 'Fan']
[32.3, 33.6, 34.2, 36.3, 34.1, 32.3, 33.6, 33.5, 33.2, 33.3, 33.3, 8470, 'Fridge']
[32.3, 34.6, 35.2, 36.3, 34.1, 32.1, 33.6, 33.3, 33.2, 33.3, 33.3, 8470, 'Fridge']
[0, 129.3, 2235.6, 2236.2, 2235.5, 2232.3, 2235.6, 2234.2, 2235.2, 2235.4, 2235.6, 8903, 'WaterHeater']
[2236.4, 2235.2, 2235.6, 2236.2, 2235.5, 2232.3, 2235.6, 2234.2, 1992.5, 119.3, 0, 8903, 'WaterHeater']

final_list=[]

for l in l1:
    for i in l:
        final_list.append([i])

You will have your result in final_list.
