带*号表示接收多个参数，实际上接收一个元组

class Car(Vehicle):    #定义子类    def __init__(self,*arg):        super().__init__(4)        self._plateNumber = "粤N95598"        self._name = arg        def setPlateNumber(self,number):        self._plateNumber = number            def getDescription(self):        return "A Car with number" + self._plateNumber    def getName(self):        return self._name

car = Car('zhuo','ze','bin')car.getName()Out[27]: ('zhuo', 'ze', 'bin')

带**号表示接收一个字典：

class Car(Vehicle):    #定义子类    def __init__(self,*arg1,**arg2):        super().__init__(4)        self._plateNumber = "粤N95598"        self._name = arg1        self._price = arg2        def setPlateNumber(self,number):        self._plateNumber = number            def getDescription(self):        return "A Car with number" + self._plateNumber    def getName(self):        return self._name

car = Car('zhuo','ze','bin',a=1,b=2)car.getName()Out[30]: ('zhuo', 'ze', 'bin')car.getPrice()Out[31]: {'a': 1, 'b': 2}
