Python can’t find the all-lowercase string "secret" in the provided text. Humans have a different approach to language than computers do. This is why you’ll often want to disregard capitalization when you check whether a string contains a substring in Python. You can generalize your ...
Let’s check our first character string my_string1: print(any(c.isalpha()forcinmy_string1))# Check if letters are contained in string# True As you can see, the logical value True has been returned, i.e. our first example string contains alphabetical letters. ...

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。
