The wxPython tutorial

Internationalizationhttp://www.zetcode.com/wxpython/in18/In our example, we took 5 germam words from the dictionary.The default sort() function sorts these words this way: Sabotage,Schläfe, Sund, Säbel, Sünde. This is incorrect, because ingerman alphabet ä character precedes a character. To get thecorect sorting, we must use locale functions.locale.setlocale(locale.LC_COLLATE, ('de_DE', 'UTF8'))Here we set the german collate. We could use the LC_ALL optionor the more specific LC_COLLATE one.words.sort( lambda a,b: locale.strcoll(a, b) )The trick is to use a new compare function within the sort()function. We define an anonymous lambda function. The strcoll()function compares two strings and returns -1, 0, 1 exactly likethe default one, but it takes the locale settings (the collate) intoaccount. This way we have the correct sorting of words.Figure: CollateSimple TranslationIn the following example, we will demonstrate a very basictranslation.A programmer has two options. Either to use the GNU gettext orto use the wxPython catalogs. Both systems are compatible.wxPython has a class wx.Locale, which is a base for using9 de 12 27/04/2008 1:06
