大头目

z2 = [[0,0,0],                             #z定义法二
    [0,0,0],
    [0,0,0]]

print(z1)
print(z2)

for i in range(3):
        for j in range(3):
               
                z1[i][j] = x[i][j] + y[i][j]

                print(z1[i][j],x[i][j],y[i][j])
                print(z2[i][j],x[i][j],y[i][j])

print(x)
print(y)
