Python implements bulk modification of file name instances

The examples in this article describe how Python implements bulk modification of file names. Share to everyone for your reference. Specific as follows:

Download the storytelling "He he legend", the file name contains xxx audio download, with a script to remove it. Scripts involve Os.rename renaming methods, Str.partition method use, and regular Match,search method differences

# encoding:utf-8### file name such as: # Helong legend \d+[www.ysx8.com].mp3# #import os,refs=os.listdir (' Shan Tianfang _ The legend ') for F in fs:  ##### #方法一: Partition gets  The #1 of the useless characters. The file name is divided into 3 parts  #ls =f.partition (' [')  #2. Ls[0] to require a file name, so get ls[1:]  # dirtystring = ". Join (ls[1:])  #3. Start replacing  #newname =f.replace (dirtystring, ') + '. mp3 ')  #os. Rename (' Shan Tianfang _ Long legend/' + F, newname)  ##### #方法二: Regular gets the useless characters  Dirtymatch = Re.search (R ' \[.*?\] ', f)  if Dirtymatch:    Dirtystring=dirtymatch.group (0)    newname=f.replace (dirtystring, ') + '. mp3 '    os.rename (' Shan Tianfang _ Helong Legend/' + F, newname)  #注意: can be directly replaced with the Re.sub method does not require characters in the file name

Hopefully this article will help you with Python programming.
