Apache requires root access to the server machine, is quite complex
and requires some learning and work to setup and use.
On the other hand it is very powerful, will handle high traffic,
and can handle the requirements of most any web site, so even if
you start with a simple site you can be pretty sure it will handle
your needs in the future as your web site grows.  Because Apache
is widely used, there an many places and people that can provide
help and advice on how to run it.

A small simple custom web server built with Python will likely
only work well with a very small traffic volume and will have
very limited capabilities but is very quick to get up and running.
You can run it on a non-privileged port if you do not have
root access to your server machine.

Apache, like most general purpose web servers, supports the CGI
protocol.  You can setup Apache so that when a request is made
for a file ending with ".py", it will run the python file and
send the program's output to the client browser.  This allows
you to generate html output from the Python program.  Python's
standard lib contains the "cgi" module that will help in writing
python code for this.

There are other more efficient ways of using Python with
a web server such as mod_python, or wsgi, but cgi is probably
the simplest, and has the most "how-to" info available.
