First, don't use range(len(iterable)). It's bad practise, and you will have
to use iterable[i] all the time. Try

for i, letter in enumerate(letters):

If you are modifying a string in-place, you could change it into a list,
then back.

blankslst = list(blanks)
...
blankslst[i] = letters[i]  # or 'letter' if you used enumerate()
...
blanks = ''.join(blankslst)

Now, why are you not printing the `blanks` string again?
