reverse
(code)¶ Reverse a custom code into alpha3, country and script code

LanguageEquivalenceConverter
¶ A
LanguageEquivalenceConverter
is a utility class that allows you to easily define aLanguageReverseConverter
by only specifying the dict from alpha3 to their corresponding symbols.You must specify the dict of equivalence as a class variable named SYMBOLS.
If you also set the class variable CASE_SENSITIVE to
True
then the reverse conversion function will be case-sensitive (it is case-insensitive by default).Example:
class MyCodeConverter(babelfish.LanguageEquivalenceConverter): CASE_SENSITIVE = True SYMBOLS = {'fra': 'mycode1', 'eng': 'mycode2'}
