一次元

M = [0, 1, 2]
print(M[0])
# 0
# N^1=3

二次元

M = [[0, 1, 2], [3, 4, 5], [6, 7, 8]]
print(M[0][1])
# 1
# N^2=9

三次元

M = [[[0, 1, 2], [3, 4, 5], [6, 7, 8]], [[0, 1, 2], [3, 4, 5], [6, 7, 8]], [[0, 1, 2], [3, 4, 5], [6, 7, 8]]]
print(M[0][1][2])
# 5
# N^3=27

四次元

M = [[[[0, 1, 2], [3, 4, 5], [6, 7, 8]], [[0, 1, 2], [3, 4, 5], [6, 7, 8]], [[0, 1, 2], [3, 4, 5], [6, 7, 8]]], [[[0, 1, 2], [3, 4, 5], [6, 7, 8]], [[0, 1, 2], [3, 4, 5], [6, 7, 8]], [[0, 1, 2], [3, 4, 5], [6, 7, 8]]], [[[0, 1, 2], [3, 4, 5], [6, 7, 8]], [[0, 1, 2], [3, 4, 5], [6, 7, 8]], [[0, 1, 2], [3, 4, 5], [6, 7, 8]]]]
print(M[0][1][2][0])
# 6
# N^4=81
