[New-bugs-announce] [issue13710] hash() on string containing only null characters returns the length of the string

[Ramchandra Apte]

New submission from Ramchandra Apte <maniandram01 at gmail.com>:

If you run hash on strings containing only null characters it returns the length of the string
>>> hash("\0")
1
>>> hash("\0\0")
2
>>> hash("\0"*1000)
1000
This behaviour is not like proper hash functions.
The hashes of these strings should exhibit the avalanche effect like in a proper hash function.
