I am not sure what I need to do for this to work

I am not sure about the hyphen part

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

    def __str__(pattern):
    super().__str__(pattern)
    pattern.split(",")
    if pattern =".":
        return "dot"
    if pattern = "_":
        return "dash"
    pattern.join("_2")


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

We have some cleaning up to do.

  1. Remove super().__str__(pattern)
  2. We don't need to split our pattern variable it's already a list
  3. Need to create a data structure (list in our case) to hold our result
  4. Add a loop to go through each character in the pattern list
  5. We don't want to return "dot" or "dash" we just want to add it to our result list
  6. Return our result list joined by "-"

All together now

def __str__(self):

    result = []

    for char in self.pattern:

        if char == ".":
            result.append("dot")
        elif char == "_":
            result.append("dash")

    return "-".join(result)
