Subject: tarfile: Fix positional-only syntax in docs (GH-105770)
X-Git-Tag: v3.13.0a1~1754
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5cdd5ba49db10f05e204e7a49ce184222a93dce8;p=thirdparty%2FPython%2Fcpython.git

tarfile: Fix positional-only syntax in docs (GH-105770)

The syntax used in the current docs (a / before any args) is invalid.

I think the right approach is for the arguments to arbitrary
filter functions to be treated as positional-only, meaning that users
can supply filter functions with any names for the argument. tarfile.py
only calls the filter function with positional arguments.
