在平时处理文件的时候，都会用到模块os，今天运用os模块获取绝对路径下的文件的文件名和后缀名，这里测试文件为:
|
1
2
3
4
5
6
7
8
9
10
11
12
13
|
[root@python ~]
# cat testfile
/usr/local/application/website/test
.txt
/usr/local/application/website/test
.txt
/usr/local/bin/test
.sh
/usr/local/application/img/AEAFFEAG
.jpg
/usr/local/application/img/AEAFAGEAG
.jpg
/usr/local/application/CSS/up
.css
/usr/local/application/PNG/good
.png
/usr/local/application/img/AETTTGEAG
.jpg
/usr/local/application/CSS/main
.css
/usr/local/application/GIF/hello
.gif
/usr/local/application/js/foot
.js
[root@python ~]
#
|
接下来编写脚本:
|
1
2
3
4
5
6
7
|
[root@python ~]
# cat get_file_name.py
#!/usr/bin/env python
import
os
with
open
(
'/root/testfile'
,
'r'
) as obj:
for
line
in
obj:
print
os.path.splitext(line.strip())
[root@python ~]
#
|
运行脚本输出结果:
|
1
2
3
4
5
6
7
8
9
10
11
12
13
|
[root@python ~]
# python get_file_name.py
(
'/usr/local/application/website/test'
,
'.txt'
)
(
'/usr/local/application/website/test'
,
'.txt'
)
(
'/usr/local/bin/test'
,
'.sh'
)
(
'/usr/local/application/img/AEAFFEAG'
,
'.jpg'
)
(
'/usr/local/application/img/AEAFAGEAG'
,
'.jpg'
)
(
'/usr/local/application/CSS/up'
,
'.css'
)
(
'/usr/local/application/PNG/good'
,
'.png'
)
(
'/usr/local/application/img/AETTTGEAG'
,
'.jpg'
)
(
'/usr/local/application/CSS/main'
,
'.css'
)
(
'/usr/local/application/GIF/hello'
,
'.gif'
)
(
'/usr/local/application/js/foot'
,
'.js'
)
[root@python ~]
#

从以上可以看出，每一行为一个元组，然后继续修改get_file_name文件:
|
1
2
3
4
5
6
7
8
9
|
[root@python ~]
# cat get_file_name.py
#!/usr/bin/env python
# -*- coding:utf8 -*-
import
os
with
open
(
'/root/testfile'
,
'r'
) as obj:
for
line
in
obj:
print
"文件路径为:%s 文件后缀为:%s"
%(os.path.splitext(line.strip())[0],os.path.splitext(line.strip())[1])
[root@python ~]
#
|
再运行脚本查看结果:
|
1
2
3
4
5
6
7
8
9
10
11
12
13
|
[root@python ~]
# python get_file_name.py

这里主要是运用os模块的splitext函数功能，以'.'的分隔符将一个完整的文件进行分割成元组，然后通过元组的下标获取元组中的元素。
