Subject[PATCH v2] perf scripts python: Add Python 3 support to event_analyzing_sample.py
Date
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.
