People aren't born knowing that * is usable with lists, so the fact that they won't be born knowing about ** either is not a point against it. Wherever newbies are learning about * will soon teach them to use ** for multi-dimensional lists as well. > [[] for _ in range(5)] works just as well without adding more syntax. This doesn't add more syntax. ** is already valid syntax. It is just adding a new method to sequences. For newbies, using a list comp is not obvious or easily discoverable. -- Steve -- https://mail.python.org/mailman/listinfo/python-list
