用python複制檔案
1. 根據檔案夾的名稱複制
需要複制的檔案夾編号檔案中，每一行表示一個編号，如下所示：
> cat id.txt
...
>
目标檔案的目錄結構樹如下所示：
- Normal_data
- T1Img
- 23XIAOHEI
- 432XIAOMING
- T1ImgSegment
- 23XIAOHEI
- 432XIAOMING
- T1ImgSegmentS
- 23XIAOHEI
- 432XIAOMING
- T1Raw
- 23XIAOHEI
- 432XIAOMING
- T1Img
主要流程就是先從檔案中讀到要複制的檔案的編号，然後周遊目标檔案夾，從檔案夾名稱中切分出編号，然後進行複制操作。完整的代碼如下：

# if you want to know which id is not found, you should input the command 'python3 copyT1ById.py >> not_found.txt' in shell.
# And you will find the new file named 'not_found.txt' in which there are maybe some ids or not.
# If it is empty, all image have been found; and if not, those is not be found.
# Good luck!

2. 根據檔案夾的名稱複制并重命名
流程與上述流程類似，代碼如下：
