1)通过list(map(int,iterable))将矩阵以二维列表的形式导入。这里必须在map()外面加层list()
2)通过两层for循环遍历计算两个举证相乘。
a_x,a_y,c_y = int(input()),int(input()),int(input()) a1=[] a2 = [] for i in range(a_x): a1.append(list(map(int,input().split(' ')))) for i in range(a_y): a2.append(list(map(int,input().split(' ')))) b_list = [] for a in range(a_x): x_list = [] for c in range(c_y): x = a1[a][0]*a2[0][c]+a1[a][1]*a2[1][c]+a1[a][2]*a2[2][c] x_list.append(x) b_list.append(x_list) for m in b_list: for n in m: print(n,end=' ') print()
