Django is irrelevant here, so what you're trying to do is use Python
code to generate an image containing some text. I don't know the
specifics of that, but I know where I'd go looking, and that's Pillow.
(No, I don't mean that I'd sleep on it, although that IS often a good
idea.) Here's the docs:

https://pillow.readthedocs.io/en/5.3.x/

The ImageDraw and ImageFont modules look promising here.

I would recommend creating a stand-alone script (outside of Django and
the whole web server system) that generates and saves an image, and
only bring it into your web server once it's working.
