        self._price = 0
        self._color = ''
        self._version = ''
        self._weight = ''

    def set_title(self, title):
        self._title = title

    def get_title(self):
        return self._title

    def set_price(self, price):
        self._price = price

    def get_price(self):
        return self._price

    def set_color(self, color):
        self._color = color

    def get_color(self):
        return self._color

    def set_version(self, version):
        self._version = version

    def get_version(self):
        return self._version

    def set_weight(self, weight):
        self._weight = weight

    def get_weight(self):

    def set_ssd(self, ssd):
        self._ssd = ssd

    def get_ssd(self):
        return self._ssd

    def set_hhd(self, hhd):
        self._hhd = hhd

    def get_hhd(self):
        return self._hhd


if __name__ == '__main__':
    mac1 = ComputerInfo()
    mac1.set_title('big mac 13\'')
