magic methods [Solved]

So after looping through the pattern attribute, I am not sure how to use the .joint() function to return the required output

morse.py 
class Letter:
    def __init__(self, pattern=None):
        self.pattern = pattern
    def __str__(self): # defining a __str__ method
        for i,j in pattern: # looping through the pattern attribute
            if i =="." and j=="_": # i should be equal to "." and j equal to "_" while looping through the pattern attribute
                result= .joint() # using .joint() to join i and j to be returned as "dot-dot-dot"


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

    def __str__(self):
        output = [] #Empty string to add item insides
        for each_letter in self.pattern: #Looping through each letter in pattern
            if each_letter == ".":
                output.append("dot") #Adding items to empty list
            elif each_letter == "_":
                utput.append("dash")
            return "_".join("output")
