Nice solution! But just one hint: each of any(map(...)) calls may be replaced with a little cheaper call: "next((x for x in string.ascii_uppercase if x in data), None) is not None" (at least 'x for x in ...' has linear complexity, like any dummy iterative thing; while calling map() may take slightly more time, because it incorporates several calls to the given predicate and because of need to allocate the result tuple) though it is a bit more complex-looking and a bit longer.

Yeah, my solution is not really fast.
