[Fixed]-What is the use of gettext when django explicitly translates from .po and .mo files?

As you can see from the main point of entry in the django translation source

Django internally uses gettext to do the translations

trans_real imports gettext here here

Assuming you have the correct settings applied.

Why does django use gettext rather than make its own translation code? For the same reason, people choose to use existing libraries than write their own (maintenance, testing, etc) as well as the fact that its been around for over 20 years which means anyone coming from an existing project, would have an easier time of integrating it into django.
