Python is "dynamic" compared to, say, C or Java.  People tend to want to
classify languages in a black/white manner, putting some languages on one
side of a dividing line between "dynamic" and "static", and other
languages on the other side.  The way most people view these things,
Perl, Python, and Ruby are all "dynamic".

That doesn't mean they're all *equally* dynamic, of course -- as you
point out.  The fact they aren't all equally dynamic doesn't mean Python
isn't "dynamic" as well.

That's certainly one way to look at it -- and it does indeed seem to at
least facilitate, if not produce, "dynamic programmers".
