I should be close

Need to see how to remove the last "-"

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

    def __str__(self):
        for item in self.pattern:
            if item == ".":
                self.morse.append("dot-")
            elif item == "_":
                self.morse.append("dash-")
            else:
                continue
        print(substr(str(self.morse)), 0, -1)




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

You have a good idea, but there's a bit to do yet:

  • you need to initialize morse to an empty array in the method
  • morse doesn't need to be a class property, it can be a local variable
  • "else: continue" is not needed as that's the default behavior of a loop
  • you might use join to combine the array into a string (str might not do what you think)
  • if you join using "-" as the separator, you won't have any excess to remove
  • you need to return the final string, not print it

That last item may seem contrary to the instructions, you might want to report that as a bug in the instructions to Support.
