If you put that line of code into your actual source code, does it work? I think this might be a pdb-specific issue, since normally the comprehension should have no difficulty seeing names from its surrounding context. A minimal case will probably involve the debugger and a function with a local, unless in some way this depends on 'self' being special. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
