classmethod challenge - the out put seems legit but it cannot pass the check

here is my code:

    @classmethod
    def from_string(cls, string):
        result = []
        string = string.split("-")
        for i in string:
            if i == "dash":
                result.append("_")
            elif i == "dot":
                result.append(".")
        return cls(result)

and below is the outbput:

>>> import classmethods
>>> a = classmethods.Letter.from_string("dot-dash-dot")
>>> a
<classmethods.Letter object at 0x7efcaf8963c8>
>>> str(a)
'dot-dash-dot'
>>> print(a)
dot-dash-dot
>>> for i in a:
...     print(i)
... 
.
_
.

str, iter all seems work, so the from_string does return a Letter object with the string's content.. But it cannot pass the check. What am I doing wrong here! please check!

It looks OK to me, so I pasted the code directly into the challenge and it passed!
