numpy.ndarray.tolist
method

ndarray.tolist()
Return the array as an a.ndim-levels deep nested list of Python scalars.   nested:嵌套的

Return a copy of the array data as a (nested) Python list. Data items are converted to the nearest 
compatible builtin Python type, via the item function.  
 以(嵌套的)Python列表的形式返回数组数据的副本。通过item函数，将数据项转换为Python中最接近的兼容内置类型。（有道）


If a.ndim is 0, then since the depth of the nested list is 0, it will not be a list at all, but a simple
 Python scalar.

Parameters:    
none
Returns:    
y : object, or list of object, or list of list of object, or …
The possibly nested list of array elements.   数组元素的嵌套列表

Notes:

The array may be recreated via a = np.array(a.tolist()), although this may sometimes lose precision.
