starmap does not work
I expected output https://code.sololearn.com/c7Xx5OB9MJDD/?ref=app
It's because of the round parentheses. This will work: list(starmap(op,[(m,),(n,)])) (m) is an expression that results in m, so starmap treats it as an iterable that needs unpacking and tries to pass all letters as function arguments individually. (m,) is a tuple that contains only m, so it is passed to the function as a single string.
