Throwback to when someone shared the OG version of this meme to my uni chat, I replied with "Oh you can simply do

def is_even(n: int) -> boolean:
    if n > 0 return not is_even(n - 1)
    elif n < 0 return not is_even(n + 1)
    else return True

And instead of laughing at the joke the TA in the chat said "When you start getting internships you'll do n % 2" like I was being serious.
