How can I redirect the user after registration so that everyone has a unique personal account?

Question

Django

I somehow got these scripts that carry out registration, and in general, I can’t understand in any way:
how, after registration, each user will have his own personal account?
how do I work with each page of my personal account?
And how to make a personal account created for the user after registration?
