Eric V. Smith <e...@trueblade.com> added the comment: I don't think it's worth checking that you've passed in the correct type for the default parameter. That's not something that Python code typically does.
The error you get: AttributeError: 'tuple' object has no attribute 'append' seem pretty clear. Pass in a list instead of a tuple, and it works as expected. ---------- nosy: +eric.smith _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14233> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
