# 导入相关python包
import cv2
import os
files = os.listdir(r'...\MT-1996\texture\cutter-1\cutter1-2')
# 遍历目录，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 转为 1-2-1-1.bmp
