如何用python查找最长的单词? [英] How to find the longest word with python?

问题描述

如何使用python从一组单词中找到最长的单词? 我可以找到第一个这样的单词:

How can I use python to find the longest word from a set of words? I can find the first word like this:

'a aa aaa aa'[:'a aa aaa aa'.find(' ',1,10)]

'a'

rfind is another subset

'a aa aaa aa'[:'a aa aaa aa'.rfind(' ',1,10)]

'a aa aaa'

推荐答案

如果我正确理解了您的问题:

If I understand your question correctly:

>>> s = "a aa aaa aa"
>>> max(s.split(), key=len)
'aaa'

split()将字符串拆分为单词(由空格分隔)； max()使用内置的len()函数查找最大的元素，即字符串长度，以找出最大"的含义.

split() splits the string into words (seperated by whitespace); max() finds the largest element using the builtin len() function, i.e. the string length, as the key to find out what "largest" means.
