如何从类到实例输入提示字典？

class Student:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def get_name(self):
        return self.name

    def get_age(self):
        return self.age

student1 = Student("John", 20)
student2 = Student("Alice", 22)

input_dict = {
    "name": student1.get_name(),
    "age": student1.get_age()
}

input_prompt = "Please enter the student's {}:"
attribute = input("Please enter the attribute you want to access (name/age): ")
if attribute in input_dict:
    prompt = input_prompt.format(attribute)
    value = input(prompt)
    print("You entered:", value)
else:
    print("Invalid attribute.")
