求两个矩阵的乘法PYTHON实现

以下是两个矩阵的乘法Python实现代码：

# 定义矩阵A和B
A = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]
]
B = [
    [9, 8, 7],
    [6, 5, 4],
    [3, 2, 1]
]

# 计算矩阵A和B的乘积
def matrix_multiplication(A, B):
    # 矩阵A的行数和列数
    row_a = len(A)
    col_a = len(A[0])
    # 矩阵B的行数和列数
    row_b = len(B)
    col_b = len(B[0])
    # 初始化结果矩阵C
    C = [[0 for j in range(col_b)] for i in range(row_a)]
    # 矩阵乘法计算
    for i in range(row_a):
        for j in range(col_b):
            for k in range(col_a):
                C[i][j] += A[i][k] * B[k][j]
    return C

# 打印结果矩阵
C = matrix_multiplication(A, B)
for row in C:
    print(row)

输出结果为：

[30, 24, 18]
[84, 69, 54]
[138, 114, 90]
