Inserting Python commands into HTML documents

[Em]

Hello,

I am an extremely new member of the Python family. I had a job interview 
  where they charged me with the task of creating a (fake) corporate 
website using Python in ten days--with two left now.

The problem is that what I have read seems to say Python is a CGI 
language... Am I remiss in believing that my website is going to be 
completely run from inside a couple .PY files in the CGI-BIN?

Is there a way for it to act more like PHP, as in run Python commands 
from inside the (index|contacts|about|etc).html or at least simulate 
that behavior? (This is on a linux server and I am not to use PHP, FYI.)


Thank you all for any assistance!
