Code challenge morse.py

Maybe its my syntax, any help is greatly appreciated.

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

    def __str__(self):
        Morse = []
        for i in patterns:
            if i == ".":
            elif i == "_":
        return "-".join(Morse)

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

for i in patterns is the problem. patterns doesn't exist. You named your variable on top in singular: pattern not patterns. Also you forgot to access it with self. Finally two suggestions, lowercase the variable Morse as titlecase is usually reserved for classes and the second suggestion being for letter in pattern reads better than for i in pattern as usually single letters such as i are used as a "counter" variable and you can be more descriptive than that for better readability.

Thank you Pedro
