If you really need the list to be nested like that, you can do:
如果你真的需要像这样嵌套列表，你可以这样做：
In [2]: x
Out[2]: array([ 0. , 0.5, 1. , 1.5, 2. , 2.5, 3. , 3.5, 4. , 4.5, 5. ])
In [3]: x.reshape(-1, 1).tolist()
Out[3]: [[0.0], [0.5], [1.0], [1.5], [2.0], [2.5], [3.0], [3.5], [4.0], [4.5], [5.0]]
but x.tolist()is also a list.
但x.tolist()也是一个列表。
