**更新**基于用户定义方法的 Python 编程

Question

有人可以帮助我使用我应该使用的正确代码吗？我还没弄明白。

---

我在下面发布了代码以及我在下面收到的错误结果。有些年龄报告不正确。有人可以帮我提供正确的代码吗？感谢您抽出宝贵时间并提供任何帮助。

下面有人帮我算出他们的生日。

（莎拉 = 2000/08/01，埃里克 = 2009/08/02，卡特 = 2009/07/28，乔治亚 = 2005/09/01）

这是代码：

from datetime import date

class Person:
  def __init__(self, name, birthdate):
    self.name = name
    self.birthdate = birthdate
  


def get_age(self):
    birthdate = self.birthdate
    today = date.today()
    if today.month >= birthdate.month and today.day >= birthdate.day:
        self.age = (today.year - birthdate.year)
    else:
        self.age = (today.year - birthdate.year) - 1
    return self.age

这是结果（一些年龄测试未通过）：

我认为你在get_age() 中有逻辑错误：

  def get_age(self):
    birthdate = self.birthdate
    today = date.today()
    if today.month >= birthdate.month and today.day >= birthdate.day:
      self.age = today.year - birthdate.year
    else:
      # haven't reached birthday yet
      self.age = (today.year - birthdate.year) - 1
    return self.age
