Usually a syntax error means you missed a parentheses or something on the previous line. Check the parens on the last line of your code.

I am not sure where you get a third test that requires 3 as a solution, but it seems to me that you are not using the rules right for the Brie item.

Also, when formatting code to reply here, be sure to put a triple backtick in the beginning and in the end :)

Your toString() method should be called:

def __str__(self)

See https://docs.python.org/2/reference/datamodel.html#object.__str__

Glad to hear that :)

Then no idea; did you try what I wrote above?

And try to format your code with the github flavored markdown, so that it appears properly indented :)

Not sure about what version of Python you are using in your IDE, but here is running 2.7 and I would just avoid unnecessary parentheses; try changing just this part: g(*(signature)) into g(*signature).
