From 2d110c11497ac52d5ce9f4b116463cdb8c3f4ad5 Mon Sep 17 00:00:00 2001 From: John Snow Date: Wed, 13 May 2020 23:52:30 -0400 Subject: [PATCH] python: remove more instances of sys.version_info MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We guarantee 3.5+ everywhere; remove more dead checks. In general, try to avoid using version checks and instead prefer to attempt behavior when possible.
