php vs. perl for web development

joe johnston explains why php is more popular than mod_perl for web development. the short answer is that they solve different problems.

i've been thinking about this with regard to python recently. i'd love to learn more python, and use it in the web space, but mod_python is more like mod_perl than php, and when i'm developing web stuff, my thinking is matches the php model closer than the mod_(python|perl) model.
