Morse Code Challenge

My method str without adding the class runs fine on its own but how do I combine with the classes to produce the right output?

morse.py 
class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern
    def __str__(self, pattern):
        new_list = self.pattern.copy()
        for item in new_list:
            if item == '.':
                n=new_list.index('.')
                new_list[n]='dot'
            else:
                n=new_list.index('-')
                new_list[n]='dash'

        return "-".join(new_list)

class S(Letter):
    def __init__(self):
        pattern = ['.', '.', '.']
        super().__init__(pattern)

pattern is passed in to __init__ so it doesn't need to be passed into __str__. Also the instructions are to replace underscores with dash. You have a hyphen.
