(summary) Generate folder-subfolders (sys.argv)

1.   copy_sub_folders.py

import os
from os import walk
import shutil

olddir = '/data/share/xxx_face/identities_13/'
newdir = './13/'

shutil.copytree(olddir,newdir)

　　

2. remove_files_in_subfolder.py

import os
from os import walk
import shutil

mypath='./13/'
for (dirpath, dirnames, filenames) in walk(mypath):
    for dir in dirnames:
       for (dirpath1, dirnames1, filenames1) in walk(mypath+dir):
           for i in filenames1:
#               print(mypath+dir+'/'+i)
               os.remove(mypath+dir+'/'+i)

　　

3.  combine step1 and step2,  copy_subfolder_remove_itsfile.py

import os
from os import walk
import shutil


olddir = './identities_12/'
newdir = './12/'

shutil.copytree(olddir,newdir)

for (dirpath, dirnames, filenames) in walk(newdir):
    for dir in dirnames:
       for (dirpath1, dirnames1, filenames1) in walk(newdir+dir):
           for i in filenames1:
               print(newdir+dir+'/'+i)
               os.remove(newdir+dir+'/'+i)

　　

4. or generate the sub-folders directly   (copy_subfolder_remove_itsfile.py)

import os
from os import walk
import shutil


olddir = './identities_11/'
newdir = './11/'

'''
try:
    os.mkdir(newdir)

except OSError:
    if not os.path.isdir(newdir):
        raise
'''

for (dirpath, dirnames, filenames) in walk(olddir):
    os.mkdir(newdir+dirpath.split('/')[2],0755)

　　

5.  Improve script 4 with sys.argv

#!/usr/bin/python

import os
import sys
from os import walk
import shutil

if len(sys.argv) != 2:
    print(
        "Original image folder is identities_xxx.
"
        "This script will mkdir folder xxx and generate all of its subfolders.
"
        "For example, make folder 1 according to identities_1 , then run:
 "
        " python 4_copy_subfolder_remove_itsfile.py 1 
")
    exit()

folder_number = sys.argv[1]


olddir = "./identities_"+folder_number+"/"
newdir = "./"+folder_number+"/"

print olddir
print newdir

'''
try:
    os.mkdir(newdir)

except OSError:
    if not os.path.isdir(newdir):
        raise
'''

for (dirpath, dirnames, filenames) in walk(olddir):
    os.mkdir(newdir+dirpath.split('/')[2],0755)
