Being completely new in python I'm trying to run a command over a set of files in python. The command requires both source and destination file (I'm actually using imagemagick convert as in the example below).
I can supply both source and destination directories, however I can't figure out how to easily retain the directory structure from the source to the destination directory.
E.g. say the srcdir contains the following:
srcdir/
file1
file3
dir1/
file1
file2
Then I want the program to create the following destination files on destdir: destdir/file1, destdir/file3, destdir/dir1/file1 and destdir/dir1/file2
So far this is what I came up with:
import os
from subprocess import call
srcdir = os.curdir # just use the current directory
destdir = 'path/to/destination'
for root, dirs, files in os.walk(srcdir):
for filename in files:
sourceFile = os.path.join(root, filename)
destFile = '???'
cmd = "convert %s -resize 50%% %s" % (sourceFile, destFile)
call(cmd, shell=True)
The walk method doesn't directly provide what directory the file is under srcdir other than concatenating the root directory string with the file name. Is there some easy way to get the destination file, or do I have to do some string manipulation in order to do this?
