It's not easy to host a django project on a shared host. At least it come with a lot of problems that you have to face.
And you will need to use hostings that support a django project (Not only python). Django comes with requirements that not many hostings provide therefore i highly recommend to go with a VPS (Ubuntu for example) and host it yourself.
There is a lot of great docs for hosting a django project on a VPS and a lot of cloud services provide services for django.
