Question

I’m new to Python and could really use some help. I have a large collection of images that I’m sorting. I need every 260th image (for example: 0, 260, 520, 780, etc). I then need to relocate those images to a new folder. Here is my code so far:

import os, os.path, sys, shutil
root = '.'
dst = "/Users/Desktop"

print "/////// F I N D__A L L__F I L E S __W I T H I N __R A N G E ///////////////////"


selectPhotos = range(260, 213921)
print selectPhotos[::260]

print "/////// L I S T__O F __A L L __J P E G S ///////////////////"


for files in os.listdir("/Users/Desktop/spaceOddy/"):
   #if files.endswith(".jpg"):
     # print files


   if files.startswith(selectPhotos[]):
      print files

      shutil.move ("files", root)

My code isn’t working in two places.

1. I receive an error that I need to pass a tuple into startswith, which I don’t know how to do. I know what a tuple is but in terms of syntax I’m in the dark.

2. I don’t know much about shutil.move. If anyone knows of a better approach I’d appreciate it.

Thanks,

To move every nth image file in a directory to another directory:

#!/usr/bin/env python
from __future__ import print_function
import glob
import shutil
import sys

dstdir = "/Users/Desktop"
for file in glob.glob("/Users/Desktop/spaceOddy/*.jpg")[::260]:
    try:
        shutil.move(file, dstdir)
    except EnvironmentError as e:
        print("can't move {}, error {}".format(file, e), file=sys.stderr)
