# 类与类之间的关系:
# 1.依赖关系:
# 最轻的一种关系
# 在方法中引进另一个类的对象
# 2.关联关系.聚合关系.组合关系
# 类与类之间的关系是比较紧密的
# 3.继承关系.实现关系
# self:当前执行这个方法的对象
# 特殊成员(__init__)
1. 类名() 会⾃自动执⾏行行__init__()
2. 对象() 会⾃自动执⾏行行__call__()
3. 对象[key] 会⾃自动执⾏行行__getitem__()
4. 对象[key] = value 会⾃自动执⾏行行__setitem__()
5. del 对象[key] 会⾃自动执⾏行行 __delitem__()
6. 对象+对象 会⾃自动执⾏行行 __add__()
7. with 对象 as 变量量 会⾃自动执⾏行行__enter__ 和__exit__
8. 打印对象的时候 会⾃自动执⾏行行 __str__
9. ⼲干掉可哈希 __hash__ == None 对象就不可哈希了
