pymmh3's Introduction

PYMMH3 - a pure python MurmurHash3 implementation.

About:

This is a pure python implementation of the murmur3 hash algorithm https://code.google.com/p/smhasher/wiki/MurmurHash3 written for the times when you do not want to muck about building and installing c-modules etc.

As this is pure python performance is FAR from optimal in CPython and if that is required a real c-module such as the one found here at https://pypi.python.org/pypi/mmh3/2.3.1 is absolutely suggested!

However this module performs extremely well in case of pypy(http://pypy.org), an alternative JIT version of python.

Performance:

Bad... we need not say more ;)

But with pypy it is blazing fast compared to mmh3 :D

Testing:

Tested by hashing all lines in Jane Eyre by Charlotte Bronte in both c and with pymmh3.

Usage:

try:
    # try with a fast c-implementation ...
    import mmh3 as mmh3
except ImportError:
    # ... otherwise fallback to this code!
    import pymmh3 as mmh3
    
print mmh3.hash( 'my string of doom!', seed = 1234 )
print mmh3.hash64( 'my string of doom!', seed = 1234 )
print mmh3.hash128( 'my string of doom!', seed = 1234 )
print mmh3.hash_bytes( 'my string of doom!', seed = 1234 )
