How rename the images in folder

Question

I have 35 folders and each folder contains 50 images, and every image has a different name, like copy(3), rename, youanem and so on. I want to rename all the images in all the folders to sequence numbers, i.e. folder 0 contains 50 images, and it should give them numbers like 0-49 and the same for the rest of the folders and their images. Folder names are 0-9 and then A-Z.

Is this possible to program for it , or i have to do it manually

This is my initial try , i didnt try it completely :

from os import rename, listdir

folder = "D://images//"
fnames = listdir('.')

for fname in fnames:
    if fname.startswith(folder):
        rename(fname, fname.replace(name, '', 1))

I am not getting idea of how to give it name

Thanks

The Easiest and Cleanest, Iterate through all the files and rename with index.

import os
os.getcwd()
collection = "C:/darth_vader"
for i, filename in enumerate(os.listdir(collection)):
    os.rename("C:/darth_vader/" + filename, "C:/darth_vader/" + str(i) + ".jpg")
