replace_commas.py

import os

folder = ''

x = True
while x:
    renameables = []

    for root, dirs, _ in os.walk(folder):
        for d in dirs:
            dir_name = (os.path.join(root, d))
            renameables.append(dir_name)

    if renameables:
        for i in renameables:
            try:
                os.rename(i, i.replace(',', '_'))
            except (FileNotFoundError, PermissionError):
                print(i)
                pass
