F.A.Q.

Can I use sage in my python script?: Yes, from sage.all import * but you are bound to an old python version
python 2 or 3?: sys.version_info(major=2, minor=7, micro=13, releaselevel='final', serial=0)
migration still going on
Can I import one sagemath notebook from another?: No, but you can import python files
