On: Common Python Mistakes

[dalke]

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#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.

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

That's a reasonable deduction. Thanks!
