    #"Return a neatly formatted descriptive name.
    long_name = f"{self.year} {self.manufacturer} {self.model}"

Answer 1

class Car:
  def __init__(self,make, model, year, manufacturer):
       self.make = make
       self.model = model
       self.year = year
       self.manufacturer = manufacturer
  def get_descriptive_name(self):
     long_name = f"{self.year} {self.manufacturer} {self.model}"
     return long_name.title()

由于您没有制造商属性，因此现在抛出错误，您可以创建一个类对象并传递值并调用它不应该通过错误的函数
