Python提取转移文件夹内所有.jpg文件并查看每一帧的方法

import os
import shutil
import glob
import cv2
 
path = 'C:/Users/deepw/Desktop/testfile'
new_path = 'D:/new'
for root,dirs,files in os.walk(path): #提取文件夹下所有jpg文件复制转移到新的文件夹
  for i in range(len(files)):
    if files[i][-3:] == 'jpg' or files[i][-3:] == 'JPG':
      file_path = root + '/' + files[i]
      new_file_path = new_path + '/' + files[i]
      shutil.copy(file_path,new_file_path)
 
 
 
img_path = glob.glob('D:/new/*.jpg') #获取新文件夹下所有图片
i=1
for each in img_path:
  img = cv2.imread(each, cv2.IMREAD_UNCHANGED)
  cv2.imshow('Image', img) #顺次显示每一帧
  k=cv2.waitKey(0) #每一帧等待时间为无穷大
  if k == ord('s'): #当按s键时保存此帧，按其他键则不保存而跳到下一帧
    cv2.imwrite('D:/want/%d.jpg'%i,img,[int( cv2.IMWRITE_JPEG_QUALITY), 100])
    cv2.destroyAllWindows()
  else:
    cv2.destroyAllWindows()
  i=i+1
