From b731fc521cf78e53268e35777d836ca80e7ab305 Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Mon, 7 Oct 2019 14:07:46 -0700 Subject: bpo-38294: Add list of no-longer-escaped chars to re.escape documentation. (GH-16442) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Prior to 3.7, re.escape escaped many characters that don't have special meaning in Python, but that use to require escaping in other tools and languages. This commit aims to make it clear which characters were, but are no longer escaped.
