Python Infinity Hash Surprise

>>> inf = float("infinity") >>> inf inf >>> hash(inf) 314159 >>> hash(-inf) -314159 >>>

A Python interactive shell shows that positive and negative infinity have hash values of 314159 and -314159. The joke is that Python uses digits of pi for infinity’s hash, creating an unexpectedly mathematical programming detail that works as a nerdy reaction to something boundless or absurd.
