[ale] Thread safe coding, Java or C

[Dustin Strickland]

Sorry; having programmed quite a bit in Python, I forgot that it might not
be common knowledge. Honestly, my statement was a bit of an
over-simplification. It really depends on what you're doing and how well
you know the performance bottlenecks, including which libraries you can use
to speed things along - but that applies with any language, whether
interpreted or compiled. Please remember, I'm not claiming that Python is *as
fast as* C.

From
http://stackoverflow.com/questions/6964392/speed-comparison-with-project-euler-c-vs-python-vs-erlang-vs-haskell
:

C: 100%
> python: 692% (118% with pypy)
> erlang: 436% (135% thanks to RichardC)
> haskell: 1421%


The general consensus is that, for most purposes(considering the hardware
of today), Python isn't too much more resource-hungry than a C program that
does the same thing, and is considerably faster than other interpreted
languages. Personally, I can see several points in the script he generated
those times from(using range() instead of xrange(), etc.) that cause
unnecessary CPU usage, so the 692% figure when compared with C isn't quite
right.

With that in mind, you're probably not going to be writing highly optimized
programs in Python anyway; that's just not what it was designed for.
