Statement: with and tarfile

Question

I try to use with statement and tarfile module...

with tarfile.open('/dir/dir/dir.tar.gz', 'w:gz') as fl:
    fl.add('/dir/dir/dir/', arcname = '/')

So it shows the next:

Traceback (most recent call last):
File "", line 1, in
AttributeError: 'TarFile' object has no attribute '__exit__'

I try to create tar.gz file and close it using statement is, but it show an error. What is the problem?

Thanks!

You can use contextlib.closing, e.g.:

from contextlib import closing
with closing(tarfile.open('/dir/dir/dir.tar.gz', 'w:gz')) as fl:
    fl.add('/dir/dir/dir/', arcname = '/')

From docs:

Even if an error occurs, page.close() will be called when the with block is exited.

contextlib.closing is available since Python 2.5 (or maybe even earlier...).
