用python分割文件名 [英] Split filenames with python

问题描述

我有一些文件，只希望拆分后不剩下'foo'和'bar'.

I have files that I want only 'foo' and 'bar' left from split.

dn = "C:\\X\\Data\\"

文件

f=  C:\\X\\Data\\foo.txt
f=  C:\\X\\Dats\\bar.txt

我尝试了f.split(".",1)[0]

我想因为dn和.txt是预定义的，所以我可以减去，不. 拆分对我不起作用.

I thought since dn and .txt are pre-defined I could subtract, nope. Split does not work for me.

推荐答案

如何使用os.path中正确的路径处理方法?

How about using the proper path handling methods from os.path?

>>> f = 'C:\\X\\Data\\foo.txt'
>>> import os
>>> os.path.basename(f)
'foo.txt'
>>> os.path.dirname(f)
'C:\\X\\Data'
>>> os.path.splitext(f)
('C:\\X\\Data\\foo', '.txt')
>>> os.path.splitext(os.path.basename(f))
('foo', '.txt')
