[Tutor] how to edit program files in Python?

That's because you are using some interpreter (or wrapper) that is not
suited for the job (maybe not suited for anything, really ;)). I guess
this thing might be IDLE. I am not going into detail about why I do not
see IDLE fit for learning Python ...

... and I won't go into detail about why I do not see the book you are
... reading fit for learning Python ;).

To get to the core of your question: Just choose your favourite text
editor, write the code in a text file, save it as <something>.py and
then execute that script.

Cheers,
Nik
