But the list comp version will work as expected for mutable types, whereas the 'solution' only works for immutable types. If anything, I feel like the list comp version is the correct solution because of its reliability, whereas the multiplication form feels like either a lucky naive approach or relies on the reader to know the type of the initialising value and its mutability. -- http://mail.python.org/mailman/listinfo/python-list
