This is common HTTP / javascriot stuff - nothing related to Python.
First learn about the HTTP protocol - something you obviously need if
doing web development -, then eventually google for XMLHttpRequest (or
'ajax').
To make a long story short: the client side doesn't give a damn about
how the server-side works - it requests an url (-> read the part about
"HTTP Request" in the rfc), waits for the response (-> read the part
about "HTTP Response" in the rfc), and whatever it wants with the
response. FWIW, HTTP requests can have a "query string" containing
arguments.
From the server-side POV, your CGI script doesn't "return" anything -
it generates a HTTP response, which will be sent back to the client by
Apache.
