python过滤后缀

         extensions = ['.jpeg', '.jpg', '.png', '.bmp']
       images = []
      for root, dirs, files in os.walk(folderPath):
      for file in files:
      if file.lower().endswith(tuple(extensions)):
       relativePath = os.path.join(root, file)
       path = ustr(os.path.abspath(relativePath))
       images.append(path)
       images.sort(key=lambda x: x.lower())
      return images
