It should work as you've shown.
What should happen is that if you type Ctrl-C while the script is 
executing extractData() then Python will raise the exception and 
the function will not know what to do with it, so it raises it to the 
next level where your handler should catch it.

So what does your real handler look like?

And what does the exception that is raised look like?
