So are Javascript and Ruby.

what's an "advanced operation" ?

def avg(*args):
return float(sum(args)) / len(args))

Would my beloved wife's life depend on it, I just couldn't say what all
this garbage is supposed to mean. If that's supposed to be "superior",
I'm quite happy with my inferior favorite languages...

No, thanks. But hopefully we have Python :

Python 2.4.1 (#1, Jul 23 2005, 00:37:37)
[GCC 3.3.4 20040623 (Gentoo Linux 3.3.4-r1, ssp-3.3.2-2, pie-8.7.6)] on
linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 3 + 4
7
>>>

My calculuator even gives a pretty good answer if I divide them (without
importing anything from the __future__).

Yes, but with Python you wouldn't have to spend a
couple of weeks sitting and thinking before starting
to type that line...
