问题描述
我需要提取某个路径的父目录的名称.这是它的样子:
I need to extract the name of the parent directory of a certain path. This is what it looks like:
C:stuffdirectory_i_needsubdirfile.jpg
我想提取directory_i_need
.
推荐答案
import os
## first file in current dir (with full path)
file = os.path.join(os.getcwd(), os.listdir(os.getcwd())[0])
file
os.path.dirname(file) ## directory of file
os.path.dirname(os.path.dirname(file)) ## directory of directory of file
...
并且您可以根据需要继续多次执行此操作...
And you can continue doing this as many times as necessary...
来自os.path,您可以使用 os.path.split 或 os.path.basename:
from os.path, you can use either os.path.split or os.path.basename:
dir = os.path.dirname(os.path.dirname(file)) ## dir of dir of file
## once you're at the directory level you want, with the desired directory as the final path node:
dirname1 = os.path.basename(dir)
dirname2 = os.path.split(dir)[1] ## if you look at the documentation, this is exactly what os.path.basename does.
