使用正则表达式对python中的字符串列表进行排序

Question

是否可以使用正则表达式对字符串列表进行排序。我有一个字符串列表，如下所示，我想按版本号对它们进行排序

_(v\d+)_

当前列表

main_cam_v005_01
main_cam_v001_1001
main_cam_v008_1000
main_cam_v003_305
main_cam_v007_1007

期望列表

main_cam_v001_1001
main_cam_v003_305
main_cam_v005_01
main_cam_v007_1007
main_cam_v008_1000

Answer 1

>>> import re
>>> data = ['main_cam_v005_01',
            'main_cam_v001_1001',
            'main_cam_v008_1000',
            'main_cam_v003_305',
            'main_cam_v007_1007']
>>> sorted(data, key=lambda i: int(re.match(r'main_cam_v(\d+)_\d+', i).group(1)))
['main_cam_v001_1001',
 'main_cam_v003_305',
 'main_cam_v005_01',
 'main_cam_v007_1007',
 'main_cam_v008_1000']
