numpy - python element wise add in list of list with other list -

i checked similar problem @ sum of n lists element-wise python

but mine little bit more complicate cause adding list of list list of list

my list looks below

[[0         0.014285714 0.035600016] ,[0.014285714   0           0.038359389] ,[0.035600016   0.038359389 0]]   [[0         0.014285714 0.035600016] ,[0.014285714   0           0.038359389] ,[0.035600016   0.038359389 0]] 

so adding these 2 results has 3 3 matrix

how efficiently add these 2 lists?

can solve using numpy:

>>> = [[1, 2, 3], [1, 2, 3], [1, 2, 3]] >>> b = [[4, 5, 6], [4, 5, 6], [4, 5, 6]]  >>> numpy import array, sum  >>> list(array(a) + array(b)) [array([5, 7, 9]), array([5, 7, 9]), array([5, 7, 9])] 

or

>>> sum([a, b], axis=0)  array([[5, 7, 9],        [5, 7, 9],        [5, 7, 9]]) >>>
