Ok, but it will fail if no such file exists. – Captain'Flam Jun 25 '20 at 12:56

@Captain'Flam - Doing research is good. https://stackoverflow.com/a/30175514/447901 – lit Jun 25 '20 at 14:28
Sorry @lit, I don't understand what you mean. But what I meant, is that if there is no file matching "*.png", glog.glob will return an empty list and accessing to its first element will fail. – Captain'Flam Jun 29 '20 at 07:35
glob() returns a list, not a string. The list may be empty. The code must iterate over the list as shown by Ann Zen's answer that you selected as correct. – lit Jun 29 '20 at 14:07

Here is how you can rename each file with numbers 1 to the amount of files:

import glob, os

for n,file in enumerate(glob.glob("*.png")):
    os.rename(file, f'file{n+1}.png')
