Yes.

>> scipy.__version__
'0.2.0__220.4275'
>>> Numeric.__version__
'23.0'
Python 2.2.2 (#1, Mar 17 2003, 15:17:58)
[GCC 3.3 20030226 (prerelease) (SuSE Linux)] on linux2
Type "help", "copyright", "credits" or "license" for more information.


BTW, Is it possible to dtermine the version of ATLAS in a similar way ?
