This allows languages with gender differences to map nicely into your sentence.
== Provide a context support ==
A translator needs context for a good translation. Keep in mind you can help him/her, by using context on translation string.
We need to call module :
from gen.ggettext import sgettext as _
from gen.ggettext import sngettext as _
(if you use ngettext) # not implemented
Translation string will use context, but this will be hidden on user interface.
Translator will see the translation string and a help string without loading program.
Program will only display the string in English or with another locale.
