Similar optimization applies to other immutable objects like empty tuples as well. Since lists are mutable, that's why [] is [] will return False and () is () will return True. This explains our second snippet. Let's move on to the third one,...

第二个放的都是有1个元素的tuple,以此下去,最后一个就是放19个元素的元组,并且每一个位置可以存放2000个元组,就是free_list中第2个位置可以存放2000个含有一个元素的元组,所以如果你之前创建的是俩个元素的元组

For object to be hashable, all attributes must be hashable and 'frozen' must be True. Function field() is needed because '<attr_name>: list = []' would make a list that is shared among all instances. Its 'default_factory' argument can be any callable. For attributes of arbitrary type...
list 容器就是列表,它可以记住每次添加元素的顺序,因此可以通过索引来存取元素,list 容器允许重复; dict 容器就是字典,它里面的每项数据都是由 key-value 对组成,因此可通过 key 来存取 value。 deque 是一个双端队列,它的两端都可以添加、删除元素,它既可作为栈(stack)使用,也可作为队列(queue)使用。
