Hi guys,
I code in php for server side coding and I have seen some sites that user perl in their sites. I have also heard of some people using python, but never a live example.

I was wondering if you could explain to me why one would use perl and or python, what is it for, and would it replace php and asp.net ?

Because it sound interesting. Also are there any things that Perl and or python do that languages in the same category can not, if so what?
