a wise programmer knows to always ask the question “can i solve this problem in python using metaprogramming?” in this instance, the answer is yes:
defis_even(n: int):
s = "def is_even_helper(number: int):\n"
b = Truefor i inrange(0, abs(n)+2):
s += f"\tif (abs(number) == {i}): return {b}\n"
b = not b
exec(s)
returnlocals().get("is_even_helper")(n)
