python - 如果其他方法在类中的方法中不起作用

Question

代码在询问问题后在第 11 行终止。它确实运行 if 语句。程序也没有给出任何错误。

class Car():

    def __init__ (self, name):
        print (f"Hello and welcome {name}. You have won a Ferrari. Please enter the details below. \n")
        phone = input("Your phone number: ")
        address = input("Your home address: ")

    def sorry(self):
        print ("Hey! We are sorry, we do not ship beyond 2000 Miles.")

        response = input("Do you still want it? Yes or No? : ".upper())

        if response == "YES":
            print (f"Cool! {name}. Ride to us.")
        elif response == "NO":
            print (f"Oops! {name}. We are sorry to see you go. :(")
        else:
            "Have a Good day!"


Car1 = Car("Jack")
Car1.sorry()

Answer 1

1. 确保将用户的输入保存到类的实例变量中，而不仅仅是方法的局部变量。

self.phone = input("您的电话号码:")

通过调用 print 打印“祝你有美好的一天”响应。

切勿在函数名称和左括号之间添加空格。

所有变量名称均应小写，并可能包含下划线。

访问 sorry() 方法内的实例变量 self.name，而不仅仅是一个 null 局部变量 name。

print(f"酷!{self.name}。骑到我们这里来。")

确保您对“Do you still Want it? Yes or No? :”的回答大写，而不是问题本身大写。

response = input("你还想要吗？是还是否？:").upper()

请确保将用户名保存在构造函数中，以便稍后访问。

self.name = 名称

尝试一下:

class Car():

    def __init__ (self, name):
        print(f"Hello and welcome {name}. You have won a Ferrari. Please enter the details below. \n")
        self.name = name
        self.phone = input("Your phone number: ")
        self.address = input("Your home address: ")

    def sorry(self):
        print("Hey! We are sorry, we do not ship beyond 2000 Miles.")

        response = input("Do you still want it? Yes or No? : ").upper()

        if response == "YES":
            print(f"Cool! {self.name}. Ride to us.")
        elif response == "NO":
            print(f"Oops! {self.name}. We are sorry to see you go. :(")
        else:
            print("Have a Good day!")

ca1 = Car("Jack")
ca1.sorry()
