按字符串的一部分对字符串列表进行排序 [英] Sort list of strings by a part of the string

问题描述

我有一个具有以下格式的字符串列表:

I have a list of strings which have the following format:

['variable1 (name1)', 'variable2 (name2)', 'variable3 (name3)', ...]

...，我想根据(nameX)部分按字母顺序对列表进行排序.我将如何去做?

... and I want to sort the list based on the (nameX) part, alphabetically. How would I go about doing this?

推荐答案

要更改排序键，请使用

To change sorting key, use the key parameter:

>>>s = ['variable1 (name3)', 'variable2 (name2)', 'variable3 (name1)']
>>> s.sort(key = lambda x: x.split()[1])
>>> s
['variable3 (name1)', 'variable2 (name2)', 'variable1 (name3)']
>>> 

与 sorted 相同的工作方式:

Works the same way with sorted:

>>>s = ['variable1 (name3)', 'variable2 (name2)', 'variable3 (name1)']
>>> sorted(s)
['variable1 (name3)', 'variable2 (name2)', 'variable3 (name1)']
>>> sorted(s, key = lambda x: x.split()[1])
['variable3 (name1)', 'variable2 (name2)', 'variable1 (name3)']
>>> 

请注意，如问题所述，这将是字母顺序的排序，因此对于2位数字的组件，它不会将它们解释为数字，例如"11"将出现在"2"之前.

Note that, as described in the question, this will be an alphabetical sort, thus for 2-digit components it will not interpret them as numbers, e.g. "11" will come before "2".
