This is a pure python implementation of FNV algorithm as specified in http://isthe.com/chongo/tech/comp/fnv/.
Only works with Python 3. And Python 2 is not planned to be supported.
$ pip install fnv
import fnv
data = 'my data'
fnv.hash(data, algorithm=fnv.fnv_1a, bits=64) # uses fnv.fnv_1a algorithm
fnv.hash(data, bits=64) # fnv.fnv_1a is a default algorithm
fnv.hash(data, algorithm=fnv.fnv, bits=64)
