GTKBrowserLog_sleoper.log
GTKBrowserLog_tvmticket.log

tvmbill.log.3
tvmbill.log.4
tvmbill.log.5
tvmbillBiz.log
tvmbillBiz.log.1
tvmbillBiz.log.2
tvmbillchger.log
tvmbillchger.log.1
tvmbillchger.log.2
tvmbillchger.log.3
tvmbillchgerBiz.log
tvmcoin.log

以上是一个目录下的文件名,如何能将tvmticket.log、tvmticket.log.1、tvmticket.log.2 这3个文件的文件名提取出来存放在列表中,并且存放的顺序是['tvmticket.log.2','tvmticket.log.1','tvmticket.log']
请教各位大神如何能实现呢?

    你所需要筛选的文件的名字是固定的吗?如果固定的话,分离文件名与扩展名,然后去匹配

    file_lst = []
    for path, dir, files in os.walk('./'):
        file_lst += files
    file_count = len(file_lst) * 1.0
    for key, lst in groupby(file_lst, key=lambda x: os.path.splitext(x)[0]):
        if cmp(key, 'tvmticket') == 0:
          pass
