# 打开文件file_path="matrix.txt"file=open(file_path,"r") 1. 2. 3. 这里,我们使用open函数来打开名为matrix.txt的文件,并指定模式为r,表示只读。 步骤二:读取文件内容 接下来,我们需要读取文件中的内容。下面是代码示例: # 读取文件内容file_content=file.readlines() 1. 2. 这里,我们使用readlines函数...

第一段代码创建了一个3x3的矩阵,其中包含数字1到9。 第二段代码使用for循环逐行打印矩阵中的每一行。 矩阵- int[][] matrix+__init__()+打印矩阵() 结尾 通过以上步骤,你应该已经知道如何在Python中打印矩阵了。记得多练习,加深理解。祝你编程顺利!
```python # 创建一个示例矩阵 matrix = [[1. 2. 3], [4. 5. 6], [7. 8. 9]] # 提取主对角线值 diagonal_values = [matrix[i][i] for i in range(len(matrix))] print("矩阵:") for row in matrix: print(row) print("对角线值:") ...
