我也尝试注释掉显示错误的行，并在该代码后的每一行中不断显示错误

class Vehicle:

        self.__type=type

    def get_cost(self):
         return self.__cost
         
    def get_vehcle_id(self):
        return self.__vehicle_id
        
    def set_premium_percentage(self,type):
        if get_type()=="Two Wheeler":
            self.__premium_percentage=2
        elif get_type()=="Four Wheeler":
            self.__premium_percentage=6
        else:
            return None
        
    def calculate_premium(self,cost,premium_percentage):
        self.__premium_amount=self.get_cost()*(self.get_premium_amount()/100)
        return self.__premium_amount
        
    def calculate_vehicle_cost(self,premium_amount):
        vehicle_cost=self.get_cost()+self.calculate_premium(self.get_cost(),self.set_premium_percentage(type))
        return vehicle_cost
    
    def display_vehicle_details(self,vehicle_cost):
        print("Vehicle id=",str(self.get_vehcle_id())
        print("Type=",str(self.get_type()))
        print("Cost without Premium=",str(self.get_cost())
        print("Final Cost=",str(self.calculate_vehicle_cost())
        
v1=Vehicle(001,"Two Wheeler",117000)
v2=Vehicle(002,"Four Wheeler",625000)
v1.display_vehicle_details

解决方法

您的括号未封闭，这就是问题所在。从第37行开始。

,

您必须调整方法以将方括号括起来：

def display_vehicle_details(self,vehicle_id,type,cost,vehicle_cost):
        print("Vehicle id=",str(self.get_vehcle_id()))
        print("Type=",str(self.get_type()))
        print("Cost without Premium=",str(self.get_cost()))
        print("Final Cost=",str(self.calculate_vehicle_cost()))

然后，您将收到“ 001”的错误“ SyntaxError：invalid token”。您可以通过将001定义为字符串来解决此问题：

v1=Vehicle('001',"Two Wheeler",117000)
v2=Vehicle('002',"Four Wheeler",625000)

最终代码如下：

class Vehicle:
    def __init__(self,cost):
        self.__vehicle_id=vehicle_id
        self.__type=type
        self.__cost=cost
        self.__premium_amount=None
        self.__premium_percentage=None
        
    def get_type(self):
        return self.__type
      
    def get_cost(self):
         return self.__cost
         
    def get_vehcle_id(self):
        return self.__vehicle_id
        
    def set_premium_percentage(self,type):
        if get_type()=="Two Wheeler":
            self.__premium_percentage=2
        elif get_type()=="Four Wheeler":
            self.__premium_percentage=6
        else:
            return None
        
    def calculate_premium(self,premium_percentage):
        self.__premium_amount=self.get_cost()*(self.get_premium_amount()/100)
        return self.__premium_amount
        
    def calculate_vehicle_cost(self,premium_amount):
        vehicle_cost=self.get_cost()+self.calculate_premium(self.get_cost(),self.set_premium_percentage(type))
        return vehicle_cost
    
    def display_vehicle_details(self,str(self.calculate_vehicle_cost()))
        
v1=Vehicle('001',625000)

v1.display_vehicle_details
