Hi, I found this interface
http://home.arcor.de/mulk/projects/mascyma/download.xhtml.en I am actually have troubles to get it working. Some warnings and errors occur when I try to start it. If anybody will have a look on it na dget in running with python 2.4, please let me know. I think it is a promising project and may be there will be an interface for Yacas in Python one day?
