You just answered your own question. > inSRC = set([bio.name for bio in bios.values()]) Note that this is actually very inefficient as it first creates a list of values, then iterates over them to create a new list, and then creates a set from that result. Py3 has set comprehensions, but in Py2.5+, you might want to try .itervalues() and a generator expression instead. Stefan -- http://mail.python.org/mailman/listinfo/python-list
