I am using an old version of Windows, windows 7 to be precise and it seems to only be compatible with Python 3.4 which supports Django 2.0 but heroku doesn't support it anymore So I want to know if I can manually edit the requirements to Django 4.0 and the required Python version in github.
I haven't yet tried anything as I am new to this
Consider using docker to run your application:
https://github.com/docker/awesome-compose/tree/master/official-documentation-samples/django/
This would allow you to set your python and Django version.
