Implementing Murmur Hash 2

Implementing Murmur Hash 2 in your application is relatively straightforward. Here's a simple example in Python:

def murmur_hash_2(data, seed=0):
    """Compute the MurmurHash2 of the given data."""
    length = len(data)
    hash = seed
    offset = 0

    while offset < length:
        chunk = data[offset:offset + 4]
        if len(chunk) == 4:
            k = int.from_bytes(chunk, byteorder='little')
        else:
            k = 0
            for i in range(len(chunk)):
                k |= (data[offset + i] & 0xFF) << (8 * (3 - i))

        k *= 0x5bd1e995
        k ^= k >> 24
        k *= 0x5bd1e995
        hash *= 0x5bd1e995
        hash ^= k

        offset += 4

    hash ^= length
    hash ^= hash >> 16
    hash *= 0x5bd1e995
    hash ^= hash >> 13
    hash *= 0x5bd1e995
    hash ^= hash >> 16

    return hash
