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

[Seeteena Thoufeek]

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.

[PATCH] perf scripts python: Add Python 3 support to futex-contention.py

[Seeteena Thoufeek]

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

The "has_key()" method is deprecated in favor of the "in" operator.
So incorporate those changes here.

You have not added "from __future__ import print_function", so you're
relying on a Python 2 parsing oddity to make this work.  If anybody ever
adds a second parameter, things will break.  I think that if you really
want to support both versions (which seems like the right goal) you should
add the import and do it properly.

Thanks,

Thanks Jonathan. I have added "from __future__ import print_function"

I didn't see Jon's comment earlier.  Sorry to have given conflicting advice.  I'd not considered it a parsing oddity but I think he's correct.

There is a flip side however and that is that this oddity probably works in versions older than v2.6 which is as far back as future support exists.

I can't imagine anyone is using < 2.6 but I have no idea what PYTHON=python2 actually implies.  The other option is to switch to sys.write.stdout
which has always had more consistent semantics.

[PATCH] perf scripts python: Add Python 3 support to powerpc-hcalls.py

[Seeteena Thoufeek]

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

The "has_key()" method is deprecated in favor of the "in" operator.
So incorporate those changes here.
