为什么下列代码不能生成一个三维列表啊
谢大佬！！！

d,e,f,g,h,i,j,k,l,A,B,C = [],[],[],[],[],[],[],[],[],[],[],[]
c = [0,0]
n = [d,e,f,g,h,i,j,k,l]
for each in n:
    each = copy.deepcopy(c)
N = [A,B,C]
count = 0
for each in N:
    if count < 9:
        each = [n[count],n[count + 1],[count + 2]]
        count += 3
z = [A,B,C]
print(z)

三维数组

arr = [[[i for i in range(1, 4)] for _ in range(3)] for _ in range(3)]
print(arr)
