#题目：两个 3 行 3 列的矩阵，实现其对应位置的数据相加，并返回一个新矩阵：
X = [[12,7,3],
    [4,5,6],
    [7,8,9]]

Y = [[5,8,1],
    [6,7,3],
    [4,5,9]]

X = [[12,7,3],
    [4,5,6],
    [7,8,9]]
 
Y = [[5,8,1],
    [6,7,3],
    [4,5,9]]

a, b, c = X
a1, b1, c1 = Y
a2 = []
b2 = []
c2 = []

for i in range(3):
    a2.append(a[i] + a1[i])
    b2.append(b[i] + b1[i])
    c2.append(c[i] + c1[i])

print(a2)
print(b2)
print(c2)
