what is that interface you are using to run the script?

if you are asking about IDE, then this was a PyCharm. But IDE in that case was needed only to show step-by-step debugging. If you have python installed on your computer, then you should be able to run this script from the console, after changing account, old_password and new_password variables.

But if you do not know how to do that, I would recommend rather to wait a little bit for a user-friendly interface
