Python: Getting files into an archive without the directory?

Question

I've been learning python for about 3 weeks now, and I'm currently trying to write a little script for sorting files (about 10.000) by keywords and date appearing in the filename. Files before a given date should be added to an archive. The sorting works fine, but not the archiving

It creates an archive - the name is fine - but in the archive is the complete path to the files. If i open it, it looks like: folder1 -> folder2 -> folder3 -> files.

How can I change it such that the archive only contains the files and not the whole structure?

Below is a snippet with my zip function, node is the path where the files were before sorting, folder is a subfolder with the files sorted by a keyword in the name, items are the folders with files sorted by date.

I am using Python 2.6

def ZipFolder(node, zipdate):
    xynode = node + '/xy'
    yznode = node + '/yz'
    for folder in [xynode,yznode]:
        items = os.listdir(folder)
        for item in items:
            itemdate = re.findall('(?<=_)\d\d\d\d-\d\d', item)
            print item
            if itemdate[0] <= zipdate:
                arcname = str(item) + '.zip'
                x = zipfile.ZipFile(folder + '/' + arcname, mode='w', compression = zipfile.ZIP_DEFLATED)
                files = os.listdir(folder + '/' + item)
                for f in files:
                    x.write(folder + '/' + item + '/' + f)
                    print 'writing ' + str(folder + '/' + item + '/' + f) + ' in ' + str(item)
                x.close()
                shutil.rmtree(folder + '/' + item)
    return

I am also open to any suggestions and improvements.

Answer 1

From help(zipfile):

 |  write(self, filename, arcname=None, compress_type=None)
 |      Put the bytes from filename into the archive under the name
 |      arcname.

So try changing your write() call with:

x.write(folder + '/' + item + '/' + f, arcname = f)

About your code, it seems to me good enough, especially for a 3 week pythonist, although a few comments would have been welcomed ;-)
