1、将指定路径下文件全部重命名
需要将指定路径下的所有文件进行重命名，修改文件的属性。
import os#'''os.walk遍历指定路径，dirpath为指定路径遍历后的各子路径，dirnames为每一子路径下包含的文件夹列表，filenames为每一子路径下包含的文件列表。。os.path.split分割文件的名称和类型，类型是以.XXX结尾的文件类型。用os.path.join而不用分隔符适配不同的操作系统'''for dirpath, dirnames, filenames in os.walk(self.FilePathDir): #self.FilePathDir为文件夹路径for file in filenames:filename, type = os.path.splitext(file)os.rename(os.path.join(dirpath,file), os.path.join(dirpath, filename + '.v') )
2、修改文件时间属性
需要修改某一路径下所有文件的最后修改时间，改写了下面的例子。
