Having problem with Morse code classes, please help.

Im not getting any errors when I run this in visual Studio code I dont understand what im missing

morse.py 
class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern
    def __str__(self):
      str_list = []
      for sign in self.pattern:
        if self.pattern == '.':
          str_list.append('dot')
        elif self.pattern == '_':
          str_list.append('dash')
      final_list = '-'.join(str_list)
      return final_list

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

In your for loop you compare the self.pattern array directly to "." and "_" instead of comparing the sign variable that is actually being produced by the for loop. Which seems like a typo to me. If you replace self.pattern with sign like this:

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

    def __str__(self):
        str_list = []
        for sign in self.pattern:
            if sign == '.': # self.pattern changed to sign
                str_list.append('dot')
            elif sign == '_': # self.pattern changed to sign
                str_list.append('dash')
        final_list = '-'.join(str_list)
        return final_list


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

Then your code should work.

I ended fixing that last night lol yeah it was a typo. However even with the updated code it will not work

class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern
    def __str__(self):
      str_list = []
      for sign in self.pattern:
        if self.pattern == '.':
          str_list.append('dot')
        elif self.pattern == '_':
          str_list.append('dash')
      final_list = '-'.join(str_list)
      return final_list

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

That's strange, the code worked for me. I tested it on the challenge before I posted it.

I would recommend just restarting the challenge (using the "Restart" button found in the challenge workspace) and then you copy and paste in the code I embedded in my answer, that usually clears up any challenge bugs.

Also just as a side note the code you posted in your reply still has the typos in it.

Yeah sorry I pasted the wrong code it worked for me after refreshing. Thanks again
