Python Integer Hashing Quirk

Integers For ordinary integers, the hash value is simply the integer itself (unless it’s -1). class int: def __hash__(self): value = self if value == -1: value = -2 return value For long Python integers, things are a little trickier. For

A cropped programming reference explains how Python hashes ordinary integers, showing that -1 is changed to -2 because -1 has a special meaning internally. The joke is aimed at Python developers reacting to an unintuitive language implementation detail.
