Python

I have added the __iter__ method. what is next?

Let's make our Letter class better for our Morse code challenge. Add an iter method to the Letter class so the letter's pattern can be iterated through. You'll want to use yield or yield from.

Do not convert the pattern to dots and dashes in iter.

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

    def __iter__(self):
        xpttern = self.pttern
        yield from xpttern

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


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

Just a typo. You have self.pttern instead of self.pattern.
