Python OOP - two numbers

[ben1122]

Actually, I changed something in the seven boom and now its shorter in a little ( just realized I can do it and the code still looks good, but still long ):

    def seven_boom_range(self, small, big):
        empty = []
        if big > small:
            small, big = big, small
        if small > big:
            for i in range(1, small - big + 1):
                if "7" in str(i) or i % 7 == 0:
                    empty.append("BOOM")
                else:
                    empty.append(i)
            empty.insert(0, 0)
        return empty
