How to Convert SASS on the fly to CSS in Python?

[trizDrerneDor]

I come from a PHP-background, more specific Symfony2. Symfony2 has a feature via Assetic to autmagically convert SASS file into CSS.Now I am working on my first python project using the bottle framework, and I am wondering if there exists a likewise way to have an on-the-fly CSS-generation of SASS files.Is there an equivalent to Assetic filters in the python world?Manually running \[code\]compass\[/code\] in the background is not an option. I want to use \[code\]SASS\[/code\], but the whole ordeal should be very coy on my workflow.
