Python bulk modified file suffix sample code share

The ipad goodreader to JS file support is not very good, although can read it but always can't quit, back to the GoodReader main interface, so I need to batch JS file into plain text. For this purpose, I have made the following small application:

The code is as follows:

#-*-Coding:utf-8-*-

Import OS
def rename ():
Path = Raw_input ("Enter the folder path to process")
Print path
Old_ext = "." +raw_input ("Please enter the type of file to be processed")
Print Old_ext
New_ext = "." +raw_input ("Please enter the type of file you want to become")
Print New_ext
For (path, dirs, files) in Os.walk (path): #遍历目录树
For filename in Files:
ext = os.path.splitext (filename) [1] #取得文件类型, pay attention to it with the dot number
Print ext;
if (ext = = Old_ext):
Print "----------------"
newname = Filename.replace (Old_ext, New_ext)
OldPath = path + "\ \" + filename
NewPath = path + "\ \" + newname
Try
Os.rename (OldPath, NewPath)
Except Baseexception, E:
Print (str (e))

if __name__ = = ' __main__ ':
Rename ()
