总结一下,鉴于类似序列的数据结构的重要性,Python 通过在 __iter__ 和__contains__ 不可用时调用 __getitem__ 来使迭代和 in 运算符正常工作。第一章中的原始FrenchDeck也没有继承abc.Sequence,但它实现了序列协议的两种方法:__getitem__和__len__。参见示例 13-2。
So if I wanted to know how many objects I have in my tuple,I can use the len function. 我还可以连接元组。 I can also concatenate tuples. 所以我可以做一些像T+。 So I can do something like T plus. 我需要一个新的元组。 I need a new tuple here. 比如说9号和11号。 Let’s say ...
