Turn list of arrays into an array of lists

[Cola_Reb]

Hey everyone,

I am currently struggling with the structure of data I receive. As a result of another (not important here) function I get a list filled with numpy arrays at a large scale (about 20 thousand entries):

first_array=[array([[1, 0, 2, 4, 3]], dtype=int64),
 array([[2, 6, 8, 3, 3]], dtype=int64),
 array([[0, 0, 4, 3, 3]], dtype=int64),
 array([[4, 4, 3, 2, 3]], dtype=int64),
...]

For the further procession of this data I need this input in the reverse structure: An array of lists like the following form:

output_array=array([
       [1, 0, 2, 4, 3],
       [2, 6, 8, 3, 3],
       [0, 0, 4, 3, 3],
       [4, 4, 3, 2, 3],
....])

Is there a way of doing this in a way that keeps the computational time low?
