Python:为什么列表没有查找方法? [英] Python: Why Lists do not have a find method?

问题描述

我正在尝试为此

I was trying to write an answer to this question and was quite surprised to find out that there is no find method for lists, lists have only the index method (strings have find and index).

有人可以告诉我其背后的理由吗? 为什么字符串都有两者?

Can anyone tell me the rationale behind that? Why strings have both?

推荐答案

我不知道为什么或可能将其埋在某些PEP中，但是我确实知道2种非常基本的查找"列表方法，它们是array.index()和in运算符.您总是可以利用这2个来找到您的物品. (此外，重新模块等)

I don't know why or maybe is buried in some PEP somewhere, but i do know 2 very basic "find" method for lists, and they are array.index() and the in operator. You can always make use of these 2 to find your items. (Also, re module, etc)
