Python way to traverse directories and bulk replace filenames and directory names

The examples in this article describe Python's way of traversing directories and replacing file names and directory names in batches. Share to everyone for your reference, as follows:

#encoding =utf-8#author:walker#date:2014-03-07#summary: Deep traverse the specified directory and change the subdirectory and file name to lowercase # Note that this program is for Windows only, Windows file (folder) name is not case-sensitive import osimport os.pathimport shutil# read into the specified directory and convert to absolute path RootDir = raw_input (' root dir:\n ') RootDir = Os.path.abspath (rootdir) print (' absolute root path:\n*** ' + rootdir + ' * * *) #先修改文件名for parent, dirnames, filenames in OS. Walk (RootDir): for filename in filenames:pathfile = os.path.join (parent, filename) pathfilelower = Os.path.join (PA Rent, Filename.lower ()) if Pathfile = = Pathfilelower: #如果文件名本身就是全小写 continue print (Pathfile +---+ PAT) Hfilelower) Os.rename (Pathfile, Pathfilelower) #后修改目录名, note the Topdown parameter here. #topdown决定遍历的顺序, if Topdown is true, the directory under top is enumerated first, then the directory, and so on, #反之, recursively enumerating the deepest subdirectories, then their sibling directories, and then the parent directory. #我们需要先修改深层的子目录for parent, Dirnames, filenames in Os.walk (RootDir, Topdown=false): for dirname in dirnames:pathdir = O S.path.join (parent, dirname) Pathdirlower = Os.path.join (parent, Dirname.lower ()) if Pathdir = = Pathdirlower: #如果文件夹 The name itself is all lowercase coNtinue Print (Pathdir +---+-Pathdirlower) os.rename (Pathdir, Pathdirlower)
