如何将邻接矩阵保存到文件中？

def save_adjacency_matrix(matrix, file_path):
    try:
        # 打开文件
        file = open(file_path, "w")
        
        # 将邻接矩阵转换为字符串
        matrix_str = ""
        for row in matrix:
            row_str = " ".join(str(element) for element in row)
            matrix_str += row_str + "\n"
        
        # 写入文件
        file.write(matrix_str)
        
        # 关闭文件
        file.close()
        
        print("邻接矩阵已保存到文件：" + file_path)
    except IOError:
        print("保存文件时出错！")

# 示例调用
adjacency_matrix = [[0, 1, 0], [1, 0, 1], [0, 1, 0]]
save_adjacency_matrix(adjacency_matrix, "adjacency_matrix.txt")
