分离路径和文件名:

• os.path.split()

区分文件的名字和后缀:

• os.path.splitext()

import os
 
file_path = "D:/test/test.py"
filepath, tempfilename = os.path.split(file_path)
filename, extension = os.path.splitext(tempfilename)

python分离文件路径和文件名，文件名和后缀名

In [1]: import os

In [2]: file_path=r'E:\data\test1001.csv'

In [3]: path,file=os.path.split(file_path)

In [4]: path
Out[4]: 'E:\\data'

In [5]: file
Out[5]: 'test1001.csv'

In [6]: file_name,suffix=file.split('.')

In [7]: file_name
Out[7]: 'test1001'

In [8]: suffix
Out[8]: 'csv'

Python os模块分离路径、文件名、后缀等信息。

给定一个路径，分离出路径、文件名、文件名后缀

import os

file_path = 'D:/code/1111-auto_/compare/J001SAG5.png'

filepath, _filename = os.path.split(file_path)
filename, extension = os.path.splitext(_filename)

filepath : D:/code/1111-auto_/compare
_filename : J001SAG5.png
filename : J001SAG5
extension : .png
