Please help:)

Here is a class called Album that holds a list of songs. Add an iter method to our Album class and use yield or yield from so the songs in our album can be iterated through.

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

    def __iter__(self):
        yield from self.pattern

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

    @classmethod
    def from_string(cls, string):
        new_list = []
        my_list = string.split("_")

        for item in my_list:
            if item == 'dot':
                new_list.append('.')
            elif item == "dash":
                new_list.append("_")

        return cls(new_list)


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

The file attached isn't related to the challenge linked so I'll help with the challenge

class Album:
    def __init__(self):
        self.songs = []
    def add(self, song):
        self.songs.append(song)
    # insert your code here

    def __iter__(self):
        # solve problem here

You are needing to yield the songs stored in self.songs. Hope this helps
