As David Mertz pointed out, functions always return a single value, but that value may or may not be unpackable. So the OP's desire, that you could extend a function that was originally written returning a single scalar value to instead return multiple values, and have code that expected a single value still work the same simply isn't possible (without other major changes to Python). -CHB -- Christopher Barker, PhD Python Language Consulting - Teaching - Scientific Software Development - Desktop GUI and Web Development - wxPython, numpy, scipy, Cython
