temp1 = [[]
for i
in range(
10)]
temp2 = [temp1
for i
in range(
20)]
temp3 = [temp2
for i
in range(
30)]
for i
in range(
30):
for j
in range(
20):
for k
in range(
10):
temp3[i][j][k] =
0
但是赋值的时候还是发现是指向同一地址的 所以还得这样
matrix3d=[]
for i
in range(
30):
matrix3d.append([])
for j
in range(
20):
matrix3d[i].append([])
for k
in range(
10):
matrix3d[i][j].append(
0)
