Gee, I really hope I am a little more capable than writing it off. And
to
answer your question bluntly no I did not notice the output because
there
wasn't any. Run a python program as "python filename.py" instead
of using the interactive console, and you will not get any output
except
exceptions or anything that your code explicitly spews out.

I am reluctant to entertain more idiomatic implementations was in the
context of what to me made sense as a part of the exercise. I have
fully
and in great detail explained the rationale in the post itself.

How's this position of mine for starters :

? And if you are not sure, you could browse this as well :

Really how silly can it be when you suggest someone is taking a
position and tweaking the benchmarks to prove a point, when I am
actually quite enthusiastic about python, really like coding using it,
and it was disappointing to me just like to jack who started off this
thread that python did not do so well. In fact I would argue that it
wasn't entirely easy to actually publish the findings given the fact
that these would not have been the findings I would've been wished
for.
