Can anyone explain to me why this code doesn't work? I discovered that I should not have been passing 'pattern' to the str function, but I'm not sure why. Thank you!
class Letter:
def __init__(self, pattern=None):
self.pattern = pattern
def __str__(self, pattern):
dajoiner = "-"
result = []
for i in pattern:
if i == ".":
result.append("dot")
if i == "_":
result.append("dash")
return dajoiner.join(result)
class S(Letter):
def __init__(self):
pattern = ['.', '.', '.']
super().__init__(pattern)

class Letter:
def __init__(self, pattern=None):
self.pattern = pattern
def __str__(self):
new_pattern = []
for x in self.pattern:
if x == ".":
new_pattern.append("dot")
elif x == "_":
new_pattern.append("dash")
return "-".join(new_pattern)
class S(Letter):
def __init__(self):
pattern = ['.', '.', '.']
super().__init__(pattern)
