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

1 方法1：2 xgettext -k_ -o internation.po_en internation.py3 xgettext -k_ -o internation.po_zh internation.py4 5 6 方法2：7 find . -type f \( -name '*.py' \) -print > list8 xgettext --files-from=list -d internation -o internation.po --from-code=UTF-8

 

 

（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 
      
       , 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 
       
        \n"  14 "Language-Team: LANGUAGE 
        
         \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 
      
       , 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 
       
        \n"  14 "Language-Team: LANGUAGE 
        
         \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
