I think you've heard my sob story of how the actual code was lost (PyCharm ate it). I've made some attempts to recover that code, but honestly, at this point Peter Otten has showed my enough examples of getattr() that work with namedtuples with variable names, that I'd rather just accept that probably some tranformation of the structure I did caused the copying of values only. I remember looking at it in the debugger, but that code was convoluted and I don't think it's worth teasing out exactly what went wrong. (or figuring out how I did it in the first place) Deborah -- https://mail.python.org/mailman/listinfo/python-list
