os.path.splitext(“文件路径”)

• os.path.splitext(“文件路径”)    分离文件名与扩展名；默认返回(fname,fextension)元组，可做分片操作
• example：

• import os
  path_01='D:/User/wgy/workplace/data/notMNIST_large.tar.gar'
  path_02='D:/User/wgy/workplace/data/notMNIST_large'
  root_01=os.path.splitext(path_01)
  root_02=os.path.splitext(path_02)
  print(root_01)
  print(root_02)

  
  
  

• 结果：
  ('D:/User/wgy/workplace/data/notMNIST_large.tar', '.gar')
  ('D:/User/wgy/workplace/data/notMNIST_large', '')
