Can't go back to Python - section 15, after a PC restart



I was in the middle of a Python course:
15. Practice Makes Perfect - Is_prime

url was:

But for some reason i’m force to start the course from the beginning.
Can someone instruct me how to get back to where is was prior the restart, please?


the course was updated to the new enviroment, progress has been lost. This was announced in:
the course itself

So no, you will have to start over



Thanks for your response anyway,
