How to set up callback on functions?

Question

Python

I have a function for POST / GET requests - call_api has a callback attached to it for a certain response from the server.
There is an authorization function - login, it happens that when the login is called, the callback is triggered, handles the error and returns to the login function where it was called and performs further work, how can I do it so that when the callback is called, it exits the login function, and after the callback is processed, it repeats the login function.

Answer 1

break and return

Answer 2

Except how to rewrite the calling function in any way. And most likely, in addition to this, add another calling login.

Answer 3

login = I dare to assume authorization, storing data in the session,
check the session before using the callback
