After ticket #21404 got solved I'm noticing that the default value for the compresslevel argument is not mentioned. Maybe this can be documented too.

Hi Sworddragon,

Thank you

At tarfile, but the compresslevel argument is mentioned there but not its default value.

Here is trivial fix for this issue. This is my first patch and I hope that it gets accepted and integrated.

hamza@hamza-ub94:~/git/cpython$ grep compresslevel Lib/
    def gzopen(cls, name, mode="r", fileobj=None, compresslevel=9, **kwargs):
            fileobj = gzip.GzipFile(name, mode + "b", compresslevel, fileobj)
    def bz2open(cls, name, mode="r", fileobj=None, compresslevel=9, **kwargs):

For gzip compression, there is also a proposal to change the default: Issue 26253.

Anyway, the patch looks good for now.
