如何将二维数组(矩阵)传入函数？

def matrix_addition(matrix1, matrix2):
    result = []
    for i in range(len(matrix1)):
        row = []
        for j in range(len(matrix1[0])):
            row.append(matrix1[i][j] + matrix2[i][j])
        result.append(row)
    return result

# 示例二维数组
matrix1 = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]
]

matrix2 = [
    [9, 8, 7],
    [6, 5, 4],
    [3, 2, 1]
]

# 将二维数组传递给函数
result_matrix = matrix_addition(matrix1, matrix2)

# 输出结果
for row in result_matrix:
    print(row)
