Subject: [PATCH v2] perf scripts python: Add Python 3 support to event_analyzing_sample.py
Date:   Thu, 17 Jan 2019 15:15:29 +0530
In-Reply-To: <1547718344-27382-1-git-send-email-s1seetee@linux.vnet.ibm.com>
References: <1547718344-27382-1-git-send-email-s1seetee@linux.vnet.ibm.com>
Message-Id: <1547718344-27382-2-git-send-email-s1seetee@linux.vnet.ibm.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Support both Python 2 and Python 3 in event_analyzing_sample.py. ``print``
is now a function rather than a statement. This should have no functional
change.

Fixes indentation issue, replace spaces with tab. The "has_key()" method
is deprecated in favor of the "in" operator. So incorporate those changes
here.
