Right Output for the code challenge But it says its wrong?

I am getting the output "dot-dot-dot".

But I can not complete this challenge because I am getting everytime the following error:

Bummer: Didn't get the right string output. Got: dot-dot-dot for S()

Tried with two different def str(self) methods:

  1. def str(self): string = "" counter = 0 for m in self.pattern: if m == ".": string += "dot" if m == "_": string += "dash" if counter != (len(self.pattern)-1): string += "-" counter += 1 return string
    1. def str(self): return str(self.pattern).replace('.','dot').replace(', ','-').replace('[','').replace(']','').replace('\'','')
morse.py 
class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern


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


    def __str__(self):
        return str(self.pattern).replace('.','dot').replace(', ','-').replace('[','').replace(']','').replace('\'','')

You're close, but:

  • the method was added to "S", but the instructions say "to add a __str__ method to the Letter class ..."
  • they also say that the method should return "dash" for every "_" (underscore)

The "Bummer" may be a bit misleading since the second problem is detected when testing letters other than "S".
