Cheap web hosting providers who only give you a directory to put stuff in are designed for running PHP applications and it isn't possible to use mod_wsgi with them as part of the common Apache instance as it isn't safe to use mod_wsgi in such shared virtual hosting providers with the way they do things.
If they provide a way of running separate long lived services (which is highly unlikely), then you might be able to use mod_wsgi-express to run a separate Apache/mod_wsgi instance, but this is still dependent on them providing a way to setup up a proxy definition in the front end Apache. Usually this isn't possible since can't do it from a .htaccess file alone.
I would suggest you go look at a different hosting provider such as Heroku or Digital Ocean and get a more capable hosting system.
