for lujing, liebiao, wenjian in os.walk(url):
for a in wenjian:

   patha = lujing + '\\' + a
   print(patha)
   name=lujing + '\\' + f'修改后{a}'
   print(name)


   img = Image.open(patha)
   array = np.array(img)
   rows = len(array)
   cols = len(array)

   # 图片尺寸
   print(rows)
   print(cols)

   # 设置图片修改后图片颜色作者这里设置为白色

   colorl =

   # 依次遍历我们需要修改颜色的图片区域
   for col in range(20, 920):
         for row in range(900, 1060):
            array = colorl
   new_img = Image.fromarray(array)
   # new_img.show()
   new_img.save(name)
for循环里输入像素即可
