本文探讨了Python中类的概念，解释了类如何作为定义对象的蓝图，而不包含实际内容。通过实例展示了如何修改类属性，例如在Email类中发送邮件状态的变化。

It’s important to note that a class just provides structure—it’s a blueprint for how something should be defined, but it doesn’t actually provide any real content itself. The Animal() class may specify that the name and age are necessary for defining an animal, but it will not actually state what a specific animal’s name or age is.

Modifying Attributes

You can change the value of attributes based on some behavior:

>>> class Email:
...     def __init__(self):
...         self.is_sent = False
...     def send_email(self):
...         self.is_sent = True
...
>>> my_email = Email()
>>> my_email.is_sent
False
>>> my_email.send_email()
>>> my_email.is_sent
True
