I was curious to know if Python would let you execute a lambda immediately by wrapping it with parens and giving it the input, such as (lambda)(input) and ... sure enough you can. As such, I present this monstrosity in 1 line:
(lambda)(input)
(lambda seats: print(f"Highest: {max(seats)}\nYour seat: {next(filter(lambda x: x not in seats, range(min(seats), max(seats))))}"))([(int("".join(map(lambda x: "1" if x in "BR" else "0", s.rstrip())), 2)) for s in open("day5.txt")])
