Question

Hi guys have a problem with renaming a set of files in separate folder in python. i have a folder structure like

images/p_0/aaa.jpg,bbb.jpg
images/p_1/aaa.jpg,bbb.jpg
images/p_2/aaa.jpg,bbb.jpg

I need to rename these jpg to like

images/p_0/A-1.jpg,B-1.jpg
images/p_1/A-2.jpg,B-2.jpg
images/p_2/A-3.jpg,B-3.jpg

and i am using the os.rename method. I just don’t get how to cycle through the folders and find the image and rename it.

Answer 1

Use os.walk and os.rename.

import os
for root, dirs, files in os.walk(top, topdown=False):
    for name in files:
        #Rename your files and use os.path.join(root, name)
