>PHP/Apache provides a very simple routing model that correlates 1:1 with the filesystem.
Might that give students a false impression of what a webserver does and is capable of doing? The students can implement the same thing themselves in a few lines of python, rather than offload most of the functionality to a monolithic and unapproachable black box like apache or nginx.
It's useful to black box some of the things when you are first learning. The specifics of serving a request are probably not the first thing you want to teach, especially when it requires some notional understanding of threading/blocking which Apache can take care of automatically. Also mod_rewrite and .htaccess provide powerful methods of adjusting behaviour of routing and the like.
Writing web apps or servers are two different things. well, mostly ... almost, at least if you teach for productive use.
especially for anyone who just started coding, a few lines of python can be a lot, so KISS.
