Change "Immediate Window/Workspace" Type



I use C9 to write blog in nodejs before.
But now , this blog was replaced by Hexo,a well-known blog sample in nodejs.

And Now , I want to program in Python in the same workspace.
But In Dashboard page,the workspace showed as a nodejs workspace.
Can I change it into a Python workspace without any data moving?
Or Can I change my immediate window from javascript to python or shell?

Thanks for your help!
