<p>It's generally considered bad practice to mutate arguments in functions. I would remove "s=s.lower()" and instead change "for x in s" to "for x in s.lower()"</p>

<p>You're right! This was actually one of my first python functions ever. So this code had a lot of lines to see the output of every method used. I probably forgot to merge this too, when I put them all together. Thank you for your input!</p>
