setting an array element with a sequence using np.zeros

Question

I have two lists which are something like the below:

How can I put two of these lists in a list in the shape below:

final : [[],[]]

I did something like the below, but I encounter this error: "setting an array element with a sequence. The requested array would exceed the maximum number of dimension of 1."

final = np.zeros((2,len(list))
final[0]=List_1
final[1]=List_2

List_1 & List_2:

Answer 1

Are the two lists of same size?

If so, try this:

final = np.array([List_1, List_2])

This will give you a numpy array of shape = (2, len(List_1))

Answer 2

You can't change the array size in numpy directly, but a list can.

final = np.zeros((2,len(List_1))
final = list(final)
final[0]=List_1
final[1]=List_2
