Python_API_File and Directory Access_os.path.splitext

API文档：

os.path.splitext(path)

Split the pathname path into a pair (root, ext) such that root + ext == path, and ext is empty or begins with a period and contains at most one period. Leading periods on the basename are ignored; splitext('.cshrc') returns ('.cshrc', '').

翻译文档：

分离文件后缀名。例如
print os.path.splitext('C:/asasdfsaf.txt')

输出：('C:/asasdfsaf', '.txt')

例子：

#! /usr/bin/env python
#coding=utf-8

import os

pathStr = 'c:/'

fList = [os.path.normcase(f) for f in os.listdir(pathStr)]
print fList
fList = [os.path.join(pathStr,f) for f in fList]
print fList
fList = [os.path.splitext(f) for f in fList]
print fList

print os.path.splitext('C:/asasdfsaf.txt')

输出：

['$recycle.bin', '360downloads', '360sandbox'...]
['c:/$recycle.bin', 'c:/360downloads', 'c:/360sandbox'...]
[('c:/$recycle', '.bin'), ('c:/360downloads', ''), ('c:/360sandbox', '')...]
