leading zeros

[kerzol81]

I figured it out. The error was that the folder var needed a full path...

import os

folder = "/home/zoli/PycharmProjects/leadingZeros/Scott.Ross_Goldberg.Variations/"
os.chdir(folder)

for i in os.listdir(folder):
   filename, extension = (os.path.splitext(i))
   filenumber = (filename.split('.')[0].zfill(2))
   filename = (filename.split('.')[1])
   new_filename =('{}.{}{}'.format(filenumber, filename, extension))
   #print(new_filename)
   os.rename(i, new_filename)

Thanks for your help, I really needed to change into that directory. What I don't understund is, that if the script was able to change into that dir, and print the corrected filenames, why it needed an absolute path for the renaming.
