Are you using "the nullary constructor list()" to mean "the 0-argument function list() that appears later in the script", and "the other one which takes a sequence" to mean the builtin function list()"??? If, so I guess it's not just newcomers to the English language who would be struggling to comprehend :-) > And the Python docs dont give a good example of dealing with > taking a sequence of args and converting it to a list.

There is nothing at all special about a sequence of args. It's just a tuple, as documented and discoverable: | >>> def func(*args): | ... print type(args), repr(args) | ... | >>> func(1,2,3,4) | <type 'tuple'> (1, 2, 3, 4) | >>> Here's a tip: when you get into a pickle like that, try running pychecker and/or pylint over your code. Here's what pychecker has to say: metaperllist.py:4: Invalid arguments to (list), got 1, expected 0 metaperllist.py:10: (list) shadows builtin HTH, John -- http://mail.python.org/mailman/listinfo/python-list
