Sure you can that's just inverting the logic.
And since it saves a variable its probably preferable.
In fact, you don't need the elif, a simple else will suffice.
And of course the last line would more idiomatically be
n += 1
But it still doesn't address Mark's point about not
identifying 'am' as a separate word... Which was
explicitly stated as a requirement in your original
post:
"...to find the index of every occurrence *word* "am" ..."
