[PATCH 27/35] perf script python: Add Python3 support to event_analyzing_sample.py

From: Arnaldo Carvalho de Melo
Date: Thu Mar 07 2019 - 12:46:44 EST


From: Tony Jones <tonyj@xxxxxxx>

Support both Python2 and Python3 in the event_analyzing_sample.py script

There may be differences in the ordering of output lines due to
differences in dictionary ordering etc. However the format within lines
should be unchanged.

The use of 'from __future__' implies the minimum supported Python2 version
is now v2.6
