Why is the default python hash not deterministic?
Why Python’s Default hash() Is Not Deterministic Python’s built-in hash() is intentionally non-deterministic across process runs for security reasons. This design protects against hash-flooding attacks but makes hash() unsuitable for stable identifiers, persistence, or cross-process coordination. As a result, developers must introduce explicit hashing strategies, which adds extra complexity and boilerplate code that would otherwise be unnecessary.
