From 15ae75d660befe643ed42eb2707a557cea97256c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ricardo=20B=C3=A1nffy?= Date: Mon, 7 Oct 2019 21:54:35 +0100 Subject: bpo-38294: Add list of no-longer-escaped chars to re.escape documentation. (GH-16442) 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. --- Doc/library/re.rst | 8 +++++--- Doc/tools/susp-ignored.csv | 1 + .../next/Documentation/2019-09-27-23-37-41.bpo-38294.go_jFf.rst | 1 + 3 files changed, 7 insertions(+), 3 deletions(-) create mode 100644 Misc/NEWS.d/next/Documentation/2019-09-27-23-37-41.bpo-38294.go_jFf.rst diff --git a/Doc/library/re.rst b/Doc/library/re.rst index df29c4d..7c950bf 100644 --- a/Doc/library/re.rst +++ b/Doc/library/re.rst @@ -931,8 +931,8 @@ form.
