I understood that I would like to receive a two-dimensional array of NxK.

n = int(input())
k = int(input())

data = []
for i in range(n):
    data.append([])
    for j in range(k):
        data[-1].append(input())

print(data)

I think it'd be good to do it like this

n = int(input())
k = int(input())

arr= []
for i in range(n):
    arr.append(list(map(int,input().split())))
