From 8dfac2edb2146d87b25543c70e25723f3d4dbd60 Mon Sep 17 00:00:00 2001 From: John Snow Date: Thu, 28 May 2020 18:21:29 -0400 Subject: [PATCH] python/qemu: delint; add flake8 config MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Mostly, ignore the "no bare except" rule, because flake8 is not contextual and cannot determine if we re-raise. Pylint can, though, so always prefer pylint for that.
