os.path.splitext，Path

• 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', '')

 

想要获取后缀即可加上[-1]
