I've tried with
print pool.map(f, range(10))
instead of
pool.map(f, range(10))
calling python file.py
In the notebook, the output must be caughted and printed for user, I
think.

I was trying with pool.map(f, range(10)); #

ipython is separate from parallel python?
What about the @parallel decorator, is that parallel python?
Its confusing in SAGE sometimes what needs importing and what doesn't.
