import cv2

import os

files = os.listdir(r'...\MT-1996\texture\cutter-1\cutter1-2')

# 遍歷目錄，并重命名

for file in files:

original = r'...\MT-1996\texture\cutter-1\cutter1-2'+os.sep+file

new_tail= ''.join([file.split('-')[0],'-2','-',file.split('-')[2],'-',file.split('-')[3]])

new = r'...\MT-1996\texture\cutter-1\cutter1-2'+os.sep++os.sep+new_tail

os.rename(original, new)

效果：
1-1-1-1.bmp 轉(zhuǎn)為 1-2-1-1.bmp
