[Coda]

The core problem there is that you've got a single string in parentheses instead of a tuple full of strings for the "hi"'s. So instead of checking to see if the user's input is one of a list of options, it's checking to see if the user's input is contained as a substring within that string. And the empty string (which is what you get if you just press enter) is contained as a substring within ALL strings.
