'classmethod' object not callable

Without seeing the entire code to be sure. If you're calling a class' method, you need to define which class is you're calling it from. Something like:

Class Foo:
    self.bar():
        return baz

# You'd can't just call bar() alone. You'd have to define which class' method is it like:
a = Foo.bar()

Does this help?

Thanks for the reply Rich. I'm trying to call test a method inside a class method. Here's the code I copied and pasted into Terminal:

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

    def __iter__(self):
        yield from self.pattern

    def __str__(self):
        output = []
        for blip in self:
            if blip == '.':
                output.append('dot')
            else:
                output.append('dash')
        return '-'.join(output)

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

And here's the method I'm trying to test:

ns = from_string(Letter, 'dot-dash-dot-dot-dash-dot')

When I type "ns" at the command prompt, I'm expecting to see output of ['.', '', '.', '.', '', '.']. Instead I'm getting the TypeError.

TypeError: 'classmethod' object is not callable

So, again, just not sure what I'm doing wrong.

It should work with

ns = Letter.from_string('dot-dash-dot-dot-dash-dot')

I believe

That one gave me

AttributeError: type object 'Letter' has no attribute 'from_string'

Brian, I am looking through comments on this challenge to find an answer to your question. I had a similar one in that i initially tried calling the super class' (Letter) from_string() method from an S() instance. I couldn't get it to work. Then, I found an answer I posted here: https://teamtreehouse.com/community/debugging-3

The answer calls it without S(), i.e., only using Letter(). So, I went with that for now, but was confused as to the purpose of including the S class at all in that challenge....probably to confuse dummies like me ;)

Lastly, I, too, did lots of research trying to figure out how, but I never found a solution with class methods using @classmethod

:(
