What do you think ‘i = i + 1’ means? (Asking because your idea of what
that means may be affecting how you expect the loop to behave.)

Try “thinking like the computer”: perform the steps yourself, reading
each statement as though you are the computer. Keep a pad and pencil at
hand, and make notes on what changes as you go through. See what
you-as-computer actually emit onto the paper, and see whether that
matches what the Python session produces.
