Why doesn't this work.

I am wondering why this won't work

morse.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, ms):
        flist =[]
        ms.replace("dash", "_")
        ms.replace("dot", ".")
        ms.replace("-", "")
        for achar in ms:
            if achar == "_" or achar == ".":
                flist.append(achar)
        return flist

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

Replace returns a value (new string with updated content). You need to assign the return value of replace to a variable for use in the for loop.
