The example of this article describes Python's method of implementing batch file name modification. Share to everyone for your reference. The specific analysis is as follows:

The following file key is to be placed in the directory to be manipulated, the following is the current directory of the image batch name, starting from 00, which is less than 10 of us in front of the name of 0, or can use the OS to set the path

?

1 2 3 4 5 6 7 8 9 10 11-12

#-*-coding:utf-8-*-import os filenames = Os.listdir (OS.GETCWD ()) for name in Filenames:print (name) for NUM in range (0 , Len (filenames)): if (num<10): Print () print (Filenames[num]) os.rename (Filenames[num], ' 0 ' +str (num) + '. png ') Else: Os.rename (FILENAMES[NUM],STR (num) + '. png ')
