Assign image names in folder to images in other folder.

[snippsat]

A example.

import os

path = r'E:\div_code\rename'
new_path = r'E:\div_code\new'
os.chdir(path)
for index,img in sorted(enumerate(os.listdir(path), 1)):
    if img.endswith('.png'):
        #print(index, img)
        os.rename(img, f'{new_path}/{index:03}.png')

See that i change to path where images are os.chdir(path),if not has to use os.path.join() in rename.
String formatting used f-string from 3.6-->.

>>> n = 5
>>> print(f'{n:03}')
005
>>> print(f'{n:08}')
00000005
>>> print(f'{n:015}')
000000000000005
