From ef9d9108917d6d5f903bca31602827e512a51c50 Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Tue, 16 Jan 2018 13:42:04 +0000 Subject: [PATCH] qapi: convert to use python print function instead of statement MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Python 3 no longer supports the bare "print" statement, it must be called as a normal function with round brackets. It is possible to opt-in to this new syntax with Python 2.6 onwards by importing the "print_function" from the "__future__" module, making it easy to support Python 2 and 3 in parallel.
