As long as you are willing to write the OS hooks in C, you can 
write the userspace device drivers in Python:

Since Python is Turing-complete, there's no reason a whole OS 
couldn't be authored in Python.

I understand there's a little trouble getting Python to prove 
that P=NP  You'll also find that it only comes close to solving 
the unrestricted three-body problem and the Traveling Salesman 
problem is still limited to fallible heuristics and searching the 
entire solution set in better than O(2**n) time.
