From 903984e5e4b32102bee095d5ff5d7b9150ccb618 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Micha=C5=82=20G=C3=B3rny?= Date: Sat, 23 May 2020 21:39:56 +0200 Subject: [PATCH] bpo-1294959: Try to clarify the meaning of platlibdir Try to make the meaning of platlibdir clear. The previous wording could be misinterpreted to suggest that it will be used to find all shared libraries on the system, and not just Python extensions. Furthermore, it was unclear whether it affects third-party (site-packages) extensions or not. The new wording tries to make its dual purpose clear, and provide the additional example of extensions in site-packages. --- Doc/library/sys.rst | 7 ++++--- Doc/whatsnew/3.9.rst | 7 +++---- Misc/NEWS.d/3.9.0a5.rst | 2 +- 3 files changed, 8 insertions(+), 8 deletions(-) diff --git a/Doc/library/sys.rst b/Doc/library/sys.rst index 98f63fb83f87a0..880f252f84aa0b 100644 --- a/Doc/library/sys.rst +++ b/Doc/library/sys.rst @@ -1141,8 +1141,7 @@ always available. .. data:: platlibdir Name of the platform-specific library directory.
