Python抽取文件

需求：要从服务器上的某个目录中抽取(复制整个目录结构)需要的文件(目录)，到其他的目录下

实现：以下是源目录结构

[root@ilovelluvia ~]# tree /teddylu
/teddylu
|-- a
|   |-- html
|   |   |-- 1.html
|   |   |-- 2.html
|   |   |-- 3.html
|   |   |-- 4.html
|   |   `-- 5.html
|   `-- images
|       |-- 10.jpg
|       |-- 1.jpg
|       |-- 2.jpg
|       |-- 3.jpg
|       |-- 4.jpg
|       |-- 5.jpg
|       |-- 6.jpg
|       |-- 7.jpg
|       |-- 8.jpg
|       `-- 9.jpg
|-- b
|   |-- html
|   |   |-- a.html
|   |   |-- b.html
|   |   |-- c.html
|   |   `-- d.html
|   `-- images
|       |-- 1.jpg
|       |-- 2.jpg
|       |-- 3.jpg
|       |-- 4.jpg
|       |-- 5.jpg
|       `-- 6.jpg
|-- c
|   |-- html
|   `-- images
|       |-- 10.png
|       |-- 1.png
|       |-- 2.png
|       |-- 3.png
|       |-- 4.png
|       |-- 5.png
|       |-- 6.png
|       |-- 7.png
|       |-- 8.png
|       `-- 9.png
`-- d
    |-- html
    `-- images

12 directories, 35 files

需要被抽取的文件列表：

[root@ilovelluvia ~]# cat list.txt
/a/html/1.html
/a/html/2.html
/a/html/3.html
/a/images
/b/html/a.html
/b/html/c.html
/c/images/1.png
/c/images/2.png
/c/images/3.png
/c/images/1997.png

脚本：

[root@ilovelluvia ~]# cat copy.py
import os
import shutil

source_root_dir='/teddylu'
target_root_dir='/lluvia'

if os.path.exists(target_root_dir):
        print(target_root_dir + ' does exist')
        shutil.rmtree(target_root_dir)
        print('##########稍等##########')
        print(target_root_dir + ' has deleted')
        os.makedirs(target_root_dir)
        print('##########稍等##########')
        print(target_root_dir + ' has created')

filename='list.txt'
with open(filename) as fl:
        for f in fl.readlines():
                f=f.strip()
                #print(f)
                source_file_path=source_root_dir+f
                target_file_path=target_root_dir+f
                #print('##########start##########')
                #print(source_file_path)
                #print(target_file_path)
                #print('##########end##########')

                if os.path.isfile(source_file_path):
                        target_list=target_file_path.split('/')[:-1]
                        #print(target_list)
                        target_new_path='/'.join(target_list)
                        #print(target_new_path)

                        os.system('mkdir -p '+ target_new_path)
                        os.system('cp '+source_file_path+' '+target_new_path+'/')
                        print('File' + target_file_path +' has copied sucessfully.')

                elif os.path.isdir(source_file_path):
                        _target_list=target_file_path.split('/')[:-1]
                        #print(_target_list)
                        _target_path='/'.join(_target_list)
                        #print(_target_path)
                        os.system('mkdir -p '+_target_path)
                        os.system('cp -r '+source_file_path+' '+_target_path)
                        print('Folders' + target_file_path +' has copied sucessfully.')

                else:
                        #print(source_file_path)
                        #print(source_file_path+ " does not exist." )
                        print('error:')
                        print(source_file_path+" does not exist")

运行和结果：
