简介

Python通过gettext模块支持国际化（i18n），可以实现程序的多语言界面的支持。

详解

Linux下Python的国际化编程

在Linux的操作和C语言的国际化过程是一样的，在需要国际化的字符串前面添加_()即可。

（1）代码：internation.py

# -*- coding: utf-8 -*-
#!/usr/bin/env python  

import gettext
locale_path = ‘./locale/‘
#gettext.install(‘internation‘, locale_path) # 这条语句会将_()函数自动放到python的内置命名空间中
zh_trans = gettext.translation(‘internation‘, locale_path, languages=[‘zh_CN‘])
en_trans = gettext.translation(‘internation‘, locale_path, languages=[‘en_US‘])  

print "----中文版本----"
zh_trans.install()
print _("Hello world!")
print _("Python is a good Language.")  

print "----英文版本----"
en_trans.install()
print _("Hello world!")
print _("Python is a good Language.")

（2）生成po文件

xgettext -k_ -o internation.po_en internation.pyxgettext -k_ -o internation.po_zh internation.py

（3）翻译（charset设定为utf-8）

　英文：

 1 # SOME DESCRIPTIVE TITLE.
 2 # Copyright (C) YEAR THE PACKAGE‘S COPYRIGHT HOLDER
 3 # This file is distributed under the same license as the PACKAGE package.
 4 # FIRST AUTHOR <[email protected]>, YEAR.
 5 #
 6 #, fuzzy
 7 msgid ""
 8 msgstr ""
 9 "Project-Id-Version: PACKAGE VERSION\n"
10 "Report-Msgid-Bugs-To: \n"
11 "POT-Creation-Date: 2015-10-08 22:06+0800\n"
12 "PO-Revision-Date: YEAR-MO-DA HO:MI+ZONE\n"
13 "Last-Translator: FULL NAME <[email protected]>\n"
14 "Language-Team: LANGUAGE <[email protected]>\n"
15 "MIME-Version: 1.0\n"
16 "Content-Type: text/plain; charset=UTF-8\n"
17 "Content-Transfer-Encoding: 8bit\n"
18
19 #: internation.py:11 internation.py:16
20 msgid "Hello world!"
21 msgstr "translate:Hello world"
22
23 #: internation.py:12 internation.py:17
24 msgid "Python is a good Language."
25 msgstr "translate:python is a good Language."

中文：

 1 # SOME DESCRIPTIVE TITLE.
 2 # Copyright (C) YEAR THE PACKAGE‘S COPYRIGHT HOLDER
 3 # This file is distributed under the same license as the PACKAGE package.
 4 # FIRST AUTHOR <[email protected]>, YEAR.
 5 #
 6 #, fuzzy
 7 msgid ""
 8 msgstr ""
 9 "Project-Id-Version: PACKAGE VERSION\n"
10 "Report-Msgid-Bugs-To: \n"
11 "POT-Creation-Date: 2015-10-08 22:06+0800\n"
12 "PO-Revision-Date: YEAR-MO-DA HO:MI+ZONE\n"
13 "Last-Translator: FULL NAME <[email protected]>\n"
14 "Language-Team: LANGUAGE <[email protected]>\n"
15 "MIME-Version: 1.0\n"
16 "Content-Type: text/plain; charset=utf-8\n"
17 "Content-Transfer-Encoding: 8bit\n"
18
19 #: internation.py:11 internation.py:16
20 msgid "Hello world!"
21 msgstr "您好！"
22
23 #: internation.py:12 internation.py:17
24 msgid "Python is a good Language."
25 msgstr "Python是一种好语言。" 

（4）建立翻译文件路径

在主文件目录下建立英文翻译路径./locale/en_US/LC_MESSAGES/和中文翻译路径./locale/zh_CN/LC_MESSAGES/ (对文件层次比较严格)。

（5）生成mo最终文件

msgfmt -o ./locale/en_US/LC_MESSAGES/internation.mo internation.po_en 

msgfmt -o ./locale/zh_CN/LC_MESSAGES/internation.mo internation.po_zh  

（6）运行
