Can't seem to get the right output for Morse.py

Hey guys, I've been on this challenge for a while now and can't seem to get the right output.

I read through some community answers and mine is practically the same as some others that have passed.

Can anyone spot where I've gone wrong?

Thank you!

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

    def __str__(self):
        output = []
        for i in self.pattern:
            if i == '.':
                output.append('dot')
            elif i == '-':
                output.appent('dash')
        return "-".join(output)

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

Ps, if anyone could show me how to properly call this in the workspace so I could test it myself that would also be great! I've tried a few combinations I found on Stack Overflow but I don't know how right they are.

:warning: Be careful about testing a challenge in an external REPL.

If you have misunderstood the challenge, it's also very likely that you will misinterpret the results.

The instructions say that your method should "return... "dash" for every "_" (underscore)", but instead of testing for underscores, your code tests for hyphens ("-").

Also, I suspect your testing did not involve any hyphens, because when adding a "dash" to the list you wrote "appent" (with a "t") instead of "append" (with a "d").

Thank you Steven!

I had to check what REPL meant but I totally agree.

I should've tried reading through the instructions a couple more times...
