python中opencv读取路径下的所有文件夹和图片

import cv2 import os

x = 0 for root, dirs, files in os.walk('C:/Course/images'):     for d in dirs:         print(d) #打印子资料夹的个数     for file in files:         print(file)         #讀入圖像         img_path = root+'/'+file         img = cv2.imread(img_path,1)         print(img_path,img.shape)                  #圖像處理~~~~~~~~~                  #保存圖像         x = x+1         img_saving_path = img_path.replace('.png',str(x)+'.png')         print(img_saving_path)         cv2.imwrite(img_saving_path,img)
