python walk 遍历文件夹 文件大小

       g = os.walk(bar_real_dir)
       img_files = ['%s/%s' % (i[0], j) for i in g if i[0].endswith('imgs') for j in i[-1] if
       j.endswith('jpg')]
  
 

筛选图片： 

      g = os.walk(list_path)
      img_files = ['%s/%s' % (i[0], j) for i in g for j in i[-1] if
       j.endswith('jpg') or j.endswith('png')or j.endswith('jpeg') ]
  
 

获取子文件个数：

      import os
      # 遍历文件夹
      def walkFile(videos_path):
       dir_count=0
       file_count=0
      for root, dirs, files in os.walk(videos_path):
      for f in files:
       file_count+=1
       print(file_count,os.path.join(root, f))
      for d in dirs:
       dir_count+=1
       print(dir_count,os.path.join(root, d))
       print(file_count,dir_count)
      if __name__ ==
