STINNER Victor <[email protected]> added the comment:
random.seed(str) uses:
if version == 2 and isinstance(a, (str, bytes, bytearray)):
if isinstance(a, str):
a = a.encode()
a += _sha512(a).digest()
a = int.from_bytes(a, 'big')
Whereas for other types, random.seed(obj) uses hash(obj), and hash is
randomized by default in Python 3.
Yeah, the random.seed() documentation should describe the implementation and
explain that hash(obj) is used and that the hash function is randomized by
default:
