multiple language support python

Question

I want to change languages on some context but it doesn't get changed until I switch off the device and then switch it on.

the function written by me:

def LanguageChange(language_t):

    language_notation = language_t.split('-')[0]

    try:

        lang = gettext.translation('abc','/home/pi/abc/locale',
               languages=[language_notation])

    except e:
        lang = gettext.translation('abc','/home/pi/abc/locale',
               fallback = True,)

    lang.install()

when I call this function in another module it doesnot change the language when already running. But when i restart the code then langauge change occurs which i have selected
