I am getting this error in the morse.py assignment: Didn't get the right string output. Got: dot-dot-dot for `S()`

My Code: class Letter: def init(self, pattern=None): self.pattern = pattern

def __str__(self):
    output = []
    for item in self.pattern:
        if item == '.':
            output.append("dot")
        elif item == '-':
            output.append("dash")
    return '-'.join(output)

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

morse.py
class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern

    def __str__(self):
        output = []
        for item in self.pattern:
            if item == '.':
                output.append("dot")
            elif item == '-':
                output.append("dash")
        return '-'.join(output)

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

Just one change to make

instead of

        elif item == '-':
            output.append("dash")

change to

        elif item == '_':
            output.append("dash")

the symbol for dash is an UNDERSCORE

On another note, whilst changing this should pass, the debugging message for the original error was unhelpful. Would it be possible for the instructors to update this?
