要更改排序键，使用的key参数：
>>>s = ['variable1 (name3)', 'variable2 (name2)', 'variable3 (name1)']
>>> s.sort(key = lambda x: x.split()[1])
>>> s
['variable3 (name1)', 'variable2 (name2)', 'variable1 (name3)']
>>>
>>>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，如问题中所述，这将是字母排序，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。
