You're right, specially for big corporations. But in the end, we're
just running in circles: it's hard to get new programmers to learn
Python, partly because it's in low demand, and partly because the
language has an totally undeserved fame of being slow. That's right -
when I talk to fellow programmers that I'm writing software in Python,
many of them are amazed and ask me, "but isn't it slow?". I've heard
it more than once... having some place that I could point them out so
they could check it for themselves (perhaps "www.pythonspeed.com"?)
would be *great*.

IMHO, Python performance is not an issue 99% of the time. I swear I
can say the same about C++. The difference between C++ and Python is
not how fast they are relatively to each other, but *where* the slow
part is. Anyone who tried to write complex code in any other language
knows that most programmers usually resort to slow but easy to
implement algorithms for things such as sorting, list handling, etc;
these parts of the code are naturally fast in Python, while others may
be faster in C++... so we're just trading "6 for half a dozen", as we
say in portuguese :-)
