Python gettext Genitiv 's

Question

I want to translate a text into German but I have trouble with the genitive 's. In German, we don't have an inverted comma after the genitive ("John's car" -> "Johns Auto" (Auto is German for car)) except the word ends with an s ("James's car" -> "James' Auto"). So, if I have the following:

_("%(name)'s car is nice") % name

The results for "John" and "James" are:

John's car is nice      -> Correct
Johns Auto ist schön    -> Correct (ist means is and schön means nice or beautiful).
James's car is nice     -> Correct
Jamess Auto is schön    -> Wrong it has to be James'

Since I'm the developer of the program, I can also update the source code and add new functions.

Answer 1

Write a function to make the genitiv:

def genitiv(name):
    if name[-1]=='s':
       return _(u"%s'" % name)
    else:
       return _(u"%s's" % name)
