Not all the time. x = , causes a syntax error, while x = (,) creates an empty tuple.

  Under both Python 2.7 and Python 3.3 I get: >>> x=(,) File "<stdin>", line 1 x=(,) ^ SyntaxError: invalid syntax

    From the Python docs (https://docs.python.org/3/tutorial/datastructures.html#tuples-and-sequences https://docs.python.org/3/tutorial/datastructures.html#tuple...) > Empty tuples are constructed by an empty pair of parentheses; And it works fine >>> x = () >>> x () I guess Herge mean that? After all, his argument was that a tuple is not always defined by the comma.

      That's a reasonable deduction. Thanks!

      There's also the distinction between x = (3) and x = (3,)
