需求：
  • 给定指定的路径，找出*~4mesh.out文件 -->Mesh的相关内容全部放在该路径下面
  • 具体格式如下：
    • StudyName， FilePath， MeshTime， SecondAttempt
实现：
  • 该段代码的亮点（心得主要如下）
    • python在读文件中每一行的时候， 格式如下的：例如“import os\n”,即在一行的末端加上一个换行符
      • 采取的方法如下：
        • 将每一行读到一个列表中，同时使用字符串的rstrip（）函数，去掉换行符，见行Line34；
        • 对列表进行操作，主要是利用查找的方式
    • 下一步，将Learning Python一书中有关文件迭代的章节要仔细的看一下
