I can't get this right.

How do I do this challenge? I can't get this to work. Here's my code.

morse.py 
class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern
        self.new_str = ''
    def __str__(self):
        new_str= ''
        for item in self.pattern:
            if item == '.':
                new_str += 'dot'
            elif item == '_':
                new_str += 'dash'
            new_str += '-'
        new_str -= '-'
        return new_str




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

You can't subtract from a string with -. You can use slice syntax to get the string without the last -:

new_str = new_str[:-1]
return new_str

or 

return new_str[:-1]
