No depth variable

    The .real part of calc's result is the weighted sum, the .imag part is the unweighted sum.

    def depthSum(self, nestedList):
        def calc(nestedList):
            s = sum(x.getInteger() * 1j if x.isInteger() else calc(x.getList())
                    for x in nestedList)
            return s + s.imag
        return int(calc(nestedList).real)

    Though less lines of code, the readability is bad...
