Maybe I don't understand the question but why would it? The browser only 
uses the stylesheet to render the page when it's specified in an html 
<style> tag.

You got me there, unless you are saying you are getting the python code 
as opposed to the html you send with req.write. Are you writing valid 
html? Any chance there is a typo in req.content_type = 'text/html'? Are 
you using a different handler for generating the html?

It would help if you can clarify your problem a little.
