Hooking python coverage during a test suite run?

I have a test suite that runs in bash, underneath this uses a number of python scripts. I want to see during the test suite how much of the python scripts are being covered.

I've looked at python-coverage but that will only work with a suite fully written in python. Does anyone know of any tool I can hook into python, give a list of scripts and on completion of the suite see coverage results?

TIA
