Python入門 ２次元配列を初期化したいのですが？

list1 = [1, 2, 3]

print(list1) # [1, 2, 3]

list1 = [0]* 3
print(list1) # [0, 0, 0]

list1 = [[0]* 3]* 3
print(list1)
# [
#     [0, 0, 0],
#     [0, 0, 0],
#     [0, 0, 0]
# ]

list = [[0 for i in range(3)] for j in range(3)]
print(list)
# [
#     [0, 0, 0],
#     [0, 0, 0],
#     [0, 0, 0]
# ]

list = np.zeros((3, 3))
print(list)
# [[ 0.  0.  0.]
#  [ 0.  0.  0.]
#  [ 0.  0.  0.]]
