amongst webapp developers, yeah. But amongst SysAdmins? Python still has a long ways to go before it reaches the stability of perl, though it's gaining. Also, CPAN is awesome. I don't know of another language that has a cpan-like tool that measures up to CPAN.

SysAdmins are slow to discard a good tool; hell, some of us still use bash. Perl 5 has been dominant for most of my career in this arena, and things will be quite slow to change.

I do see that Python is beginning to replace perl in the places where perl5 replaced bash in the earliest parts of my career... I remember back in the late '90s it was common to maintain two versions of perl on a system. Now, perl5 is stable... you almost never need more than one version of it, but I see systems (especially RHEL systems) with more than one version of python (sometimes more than two. Gah!)
