Generate translation into a django project for a specific language

get_django_translations.py

"""
This file can be used to generate translation into a django project for a specific language.
Things to keep in mind:

    - This may not work on larger files.
    - This script not be helpful for(it should be able to translate almost everything else):
        - Strings that span multiple lines.
        - Strings that contain some parameter.(e.g `msg_id "This {value} is strange"`)
    - Install googletrans using the command `pip install googletrans`(https://github.com/ssut/py-googletrans).\
        Many thanks to them for this project
    - In case, your IP get blocked by google, try to increase the sleep time.
    - Change the parameters to the translate function on line 59 as per your requirements.
    - This is not supposed to be a "end-all". Please verify your translations personally after running the script.\
        It is only meant to reduce some sort of labour not all :-p
    - Make sure that you place this file in the same directory as the translation files(`django.po` and `djangojs.po`).\
        Otherwise you will have to change the path for opening the translation files.
    - I am not sure this is completely legal. :)
