python: แปลง Singular/Plural

Topic: 
 
ใช้แปลงคำนามระหว่าง Singular/Plural รุ่นนี้ใช้ได้กับภาษาอังกฤษและเสปน ดาวน์โหลดได้ที่ http://www.bermi.org/downloads $ wget http://www.bermi.org/downloads/python_inflector-0.1.tar.gz
$ tar xfz python_inflector-0.1.tar.gz
$ cd python_inflector-0.1
$ python
Python 2.5.2 (r252:60911, Jul 31 2008, 07:39:27) 
[GCC 4.3.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import Inflector
>>> inf = Inflector.English()
>>> inf.singularize('oxen')
'ox'
>>> inf.pluralize('sheep')
'sheep'
>>>
ยังมีอีกหลายฟังก์ชั่น เอาไว้ค่อยศึกษาอีกที update
ลองใช้แล้ว ไม่ค่อยดีเท่าไหร่ กฎต่าง ๆ ยังขาดความสมบูรณ์อีกมาก
ลองปรับปรุงเล็กน้อยเฉพาะส่วนของ Singular/Plural ให้พอใช้งานจริงได้
(แต่ก็ยังไม่ดีอยู่ดี)
