I just saw this recently, but I have not yet looked at it more
(since I am currently using matlab.)
The install explanation in http://bazaar.launchpad.net/~individ/pytave/trunk/files
looks very concentrated on Posix and I'm a windows user.
However, this seems what you are looking for.
Announcing Pytave - Python to Octave extension
Embeds the Octave language interpreter as an extension to Python,
enabling existing m-files to be used from Python.
* Implicit type conversions between Python and Octave. Supports all
Numeric integer, real double (and possibly real float) matrices
* Architecture independent - no assumption on endianess or integer
Call Octave code in Python:
>>> import pytave
>>> pytave.feval(1, "cos", 0)
