python 获取文件路径相关

1、只获得路径的最后一部分

import os
os.path.basename('C:\Users\Administrator\Desktop')
Out[81]: 'Desktop'
os.path.basename('C:\Users\Administrator\Desktop\a.txt')
Out[82]: 'a.txt'

2、对目录结构的操作

import os

print '***获取当前目录***'
print os.getcwd()
print os.path.abspath(os.path.dirname(__file__))

print '***获取上级目录***'
print os.path.abspath(os.path.dirname(os.path.dirname(__file__)))
print os.path.abspath(os.path.dirname(os.getcwd()))
print os.path.abspath(os.path.join(os.getcwd(), ".."))

print '***获取上上级目录***'
print os.path.abspath(os.path.join(os.getcwd(), "../.."))

结果：

***获取当前目录***
/workspace/demo/folder/test
/workspace/demo/folder/test

***获取上级目录***
/workspace/demo/folder
/workspace/demo/folder
/workspace/demo/folder

***获取上上级目录***
/workspace/demo
