morse.py fails, but results match

The example for this challenge indicates the output should be "dot-dot-dot". The error received when checking the result is: "Bummer! Didn't get the right string output. Got: dot-dot-dot for 'S()'." That looks pretty close to the expected output. What am I missing?

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

    def __str__(self):
        ctr = 0
        output = ''
        for char in self.pattern:
            ctr += 1
            if char == '.':
                output += 'dot'
            elif char == '_':
                output += 'dash'
            if ctr < 3:
                output += '-'
        return output


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

You are assuming that the pattern will always be 3 dots/dashes long, but it could be 2 or 4. You want to just build your string and strip off the last '-'.
