Re: [Jython-users] Howto merge 2 folder into a new folder

[David H. <Dav...@sa...>]

If you have to copy subfolders too, then you need a few more lines of code:

import glob, os, shutil
for filename in glob.glob('/tmp/folder1/*') + glob.glob('/tmp/folder2/*'):
    if os.path.isdir(filename):
        shutil.copytree(filename, os.path.join('/tmp/folder3',
            os.path.basename(filename)))
    else:
        shutil.copy(filename, '/tmp/folder3')

This works as long as there aren't any subfolders or files in folder2 that have the same name a subfolder in folder1.

Hey David

Thx for the reply

I forgot (sorry) to say that folder1 and folder2 contains subfolders. And if I remember correctly then copy command expect the folder to exist already.

You got a good idea on how to solve that problem (in a elegant way)

I like the glob module.

import glob
import shutil
for filename in glob.glob('/tmp/folder1/*') + glob.glob('/tmp/folder2/*'):
shutil.copy(filename, '/tmp/folder3')

Hello

The pledge:
Howto in a platform independent copy files from 2 folders with a unknown number of files into a new folder in jython

like (in unix)
cp /tmp/folder1/* /tmp/folder3
cp /tmp/folder2/* /tmp/folder3

The turn:
(I use shutil)
shutil.copytree('/tmp/folder1/' ,  '/tmp/folder3')
shutil.copytree('/tmp/folder2/' ,  '/tmp/folder3')

The presitge:
Well not very fancy actually - I get a exception on the second call to copytree because copytree demands that target folder doesn't exsists. (I can't understand *why* it demands that)
shutil.copy doesn't accept the input to be a folder so that can't be used either

How do I turn this into a good prestige :-D
Cheers
