Python zipfile works partially on Windows?

Question

I'm using zipfile in my script to unzip .zip files. Here's my code:

def unzip(src, dst):
    zf = zipfile.ZipFile(src)
    for member in zf.infolist():
        words = filter(None, member.filename.split('/'))
        path = dst
        for word in words[:-1]:
            drive, word = os.path.splitdrive(word)
            head, word = os.path.split(word)
            if word in (os.curdir, os.pardir): continue
            path = os.path.join(path, word)
        zf.extract(member, path)
    dirMacosx = "%s/__MACOSX" % (dst)
    if os.path.exists(dirMacosx):
        shutil.rmtree(dirMacosx)

When I unzip a file on Linux or OS X, it works fine, but when I run it on Windows, it created a directory and all the directories in it, but none of the files. Why might this be?

Answer 1

For compatibility with Unix-like and Windows, replace

words = filter(None, member.filename.split('/'))

with

words = filter(None, member.filename.split(os.sep))

This will use a / on Unix-like, and a \\ on Windows.
